White LEDs Driver

for up to 2LEDs in series, 5 strings

BD6079GWL

●General Description

●Key Specification

■

Power supply voltage range:

Quiescent Current:

Switching frequency

2.3V to 5.5V

0.4µA (Typ.)

2MHz(Typ.)

BD6079GWL is a boost-up DC/DC type white LED driver

IC with synchronous rectification that can drive up to 10

LEDs, arranged in 1-5 strings of 2LEDs in Series, with

string LED Cathodes connected to GND.

Operating temperature range

-30°C to +85°C

With synchronous rectification (no external schottky diode

required) and small package, it is possible to save mount

space.

The brightness of LED can be adjusted by using PWM

pulse on EN pin. (PWM Frequency :100Hz~1600Hz)

LED current is set by resistance at ISET terminal.

●Package

UCSP50L1

W (Typ.) x D (Typ.) x H (Max.)
