EMD2050 Datasheet Pwm Step-up DC/dc Converter

Manufacturer: ESMT (Elite Semiconductor Microelectronics Technology)

Overview: ESMT/EMP EMD2050 PWM Step-Up DC/DC Converter for Panel Backlight.

General Description

The EMD2050 designed with high efficiency step up DC/DC converter for driving white LEDs.

The device can drive up 3 white LEDs from a single Li-Ion battery or a DC power 2.5V to 5.5V.

The EMD2050 uses current mode and pulse-width modulated (PWM) operation.
