Flash LED Driver, LED, and Backlighting LED Drivers
The ADP1653 is an ultra-compact, high efficiency, 12V boost converter from Analog Devices,
specifically designed and optimized for use in cellular camera phones and digital still cameras.
The ADP1653 solution consumes a mere 7.2 mm x 6.4 mm of board space while still offering high-
efficiency Flash circuitry that can drive one string of high-brightness LEDs up to 500 mA, as well as
a separate indicator LED at lower currents up to 17 mA.
Analog Devices offers LED drivers for automotive and LCD backlighting applications. Products like
the AD8240, designed for automotive applications, both drive and monitor the LED assembly. End
users are demanding bigger, brighter, and thinner displays. The ADM8845 and ADM8843 charge-
pump-based backlight drivers are designed for driving up to six and four white LEDs in parallel,
respectively, while ensuring uniform brightness of a backlit LCD display. By individually monitoring
each LED current, excellent matching performance is achieved. The ADM8845 is also designed
to maximize power efficiency by switching automatically between three charge pump modes based
on the input voltage. For applications with severe height restrictions, the ADM8843 offers an ultra-
thin package height of 0.5 mm.

                                                       Infineon Technologies’ linear-mode LED driver family, BCR401, BCR402, BCR405, and newly introduced
                                                       BCR450, provides efficient, low-cost constant-current solutions for LED strings from 10 mA to 700 mA.
                                                       Our constant-current drivers keep light emission consistent over power supply and temperature variations,
                                                       eliminate the effect of VF variation, and help prevent thermal runaway in applications. We also offer low
                                                       forward voltage schottky diodes, including single-package reverse polarity protection diode arrays (RPP).

Low-to Medium-Power LED Drivers—Inductorless
The Linear Technology family of charge pump-based LED drivers includes a wide selection of simple
and compact inductorless DC/DC converter designs. These step-up converters offer low ripple and
can be used to boost an input voltage and drive LEDs. By eliminating the inductor, these switched-
capacitor converters provide a small solution footprint and a simple design.

The LM5022 is a high voltage controller that supports boost, SEPIC,                              The LM3401 is a buck-switching controller with an external P-MOSFET
and flyback configurations. Output current regulation is based on                                switch, which allows the device to run at 100% duty cycle and continue
current-mode control, which eases the design of loop compensation                                to drive a string of LEDs when the total forward voltage drop is equal to
while providing inherent input voltage feed-forward                                              VIN. Adjustable, dual-side hysteresis allows very flexible inductor selection,

                                                LED7706 LED Driver—Monolithic Driver for up to
                                                60 White LEDs for Mobile PC LCD Panel Backlighting
                                                The LED7706 is a monolithic white LED driver specifically designed to supply LED arrays used to
                                                backlight mobile PC LCD panels. It consists of a highly-efficient boost converter integrating a power
                                                MOSFET and six controlled-current generators (ROWs). The device can manage an output voltage
                                                able to supply up to 10 white LEDs per ROW. The boost section is based on a constant switching
                                                frequency, peak-current mode architecture. The boost output voltage is controlled so that the lowest
                                                voltage of the ROW, referred to as SGND, is equal to an internal reference voltage (400 mV typ.).
                                                The typical input voltage range is from 4.5V up to 36V. In addition, the LED7706 has an internal 5V
                                                LDO regulator that supplies the internal circuitry of the device and is capable of delivering up to 40
                                                mA. The input of the LDO is the main input voltage (VBATT). The boost section switching frequency
                                                can be externally adjusted from 200 kHz to 1 MHz. It also has an internal fixed value of 660 kHz
                                                (typ.), which eliminates the need for a resistor, an important feature in minimum component-count
       LED7706 demo board                       applications. The frequency pin (FSW) can also be used as the synchronization input, allowing the
                                                LED7706 to operate both as the master or the slave. The generators can be externally programmed
                                                to sink from 16 mA up to 30 mA and can be dimmed via a PWM signal (1 percent dimming duty-
                                                cycle at 20 kHz can be managed). The device is able to detect and manage the open- and shorted-
                                                LED faults. If some ROWs are not used, during the startup the device is able to self-detect and
                                                automatically disconnect the ROWs without any fault detection. Output over-voltage, internal power
                                                MOSFET over-current, and thermal shutdown are provided as protection.

STLED316S Panel Controller—LED Display Controller
with Key-Scan for Cost-Effective Designs
ST has recently introduced the STLED316S, an integrated LED driver to help designers achieve a
more efficient and simplified design for front panels, such as those found on set-top boxes, DVD
players, washing machines, dryers, and microwave ovens. The STLED316 is an integrated LED driver
that controls front-panel activities. A typical front panel consists of a key-pad, an LED display panel,
and various discrete LEDs. The device employs a unique timemultiplexing scheme to drive displays
together with key-scans with a limited number of I/Os. The combination of display driving and key-
scanning allows the use of a single device like STLED316S for the complete front panel solution.
This eliminates the need for sub-CPU and other logics-plus discrete devices, reduces BOM count,
and lowers the final cost.

Low-Voltage LED Drivers
The TPS61165 operates over a 3V to 18V input supply and delivers an output voltage up to 38V.
It operates at a 1.2 Hz fixed switching frequency to reduce output ripple, improve conversion efficiency,
and allow for the use of small external components. The LED current can be changed using one-wire
digital or PWM signal. During dimming, the output ripple of TPS61165 at the output capacitor is small
and does not generate audible noises associated with common on/off control dimming.
These low-voltage LED drivers are optimized for getting the most life out of battery-powered applications.
