EMD2050 - PWM Step-Up DC/DC Converter

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.

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. It switches at 1.2MHz and allows using small inductor and both of input/output capacitors. An internal compensation can reduce external component. The EMD2050 include under-voltage lockout, current limit, over voltage and thermal shutdown protection. The EMD2050 is available in SOT-26 package.
