EMD2055 Datasheet Pwm Step-up DC/dc Converter

Manufacturer: ESMT (Elite Semiconductor Microelectronics Technology)

Overview: ESMT EMD2055 PWM Step-Up DC/DC Converter for Panel Backlight (10 WLEDs Driver).

General Description

The EMD2055 is a highly efficient, step-up DC/DC converter for driving white LEDs.

The device can drive up to 10 serially connected white LEDs from a single Li-Ion battery, or to drive multiple serial and parallel binations with a DC power supply from 2.5V to 5.5V.

The EMD2055 uses current mode and pulse-width modulated (PWM) operation.
