LDS8710

High Efficiency 10 LED Driver With No External Schottky

FEATURES



High efficiency boost converter with the input

voltage range from 2.7 to 5.5 V

No external Schottky Required (Internal

synchronous rectifier*)



250 mV current sense voltage

Drives one LED string with 10 LEDs in series

up to 30 mA

0.7 MHz Switching Frequency

Efficiency greater than 83%

PWM LED Dimming Control Mode

Over-voltage, under-voltage, over-current,

and over-temperature protection

Low Shutdown Current (<1µA)

Available in 2 x 3 x 0.8 mm 8-pin TDFN

package

eliminating the need for ballast resistors and factory

calibration. Operation at 0.7 MHz allows use of small

value low profile inductor (10 – 33 µH) and 1µF 50V

ceramic capacitor.



The use of integrated synchronous rectifier makes

the efficiency dependent on only inductor DC

resistance.



The supply voltage down to 2.7 V for new Li-ion

battery chemistries or two alkaline battery cells

extends the battery life. Under-voltage protection

disables the part when V_INvoltage reaches 2.0V

APPLICATION



Color Display Backlight

Portable Navigation and GPS Receivers

Smart phones

Digital Photo Frames

Portable DVD Players

The LDS8710 has thermal shutdown set at 150 C.

Above this value, the boost converter stops

switching. The part resumes normal operations when

temperature drops below 130 ⁰C.

The over-current protection provides cycle-by-cycle

current limit.

Multimedia Phones

The internal output over-voltage protection prevents

damage in the case of a faulty LED disconnect.

DESCRIPTION

The LDS8710 is a fixed frequency current mode

boost converter with internal synchronous rectifier

and cycle-by-cycle switch current limit specifically

designed to drive a string of up to 10 White LEDs

with factory preset maximum current 20, 25, or 30

mA. Series connection of the LEDs provides constant

current and subsequently uniform brightness,

The PWM control ensures brightness adjustment with

a frequency from 100 Hz up to 30 KHz.

The EN/PWM logic input functions as a chip enable

and LED current PWM contol pin.

The device is available in in 8-pin TDFN 2 x 3 mm

package with a max height of 0.8 mm.
