EMD2050
EMD2050 is PWM Step-Up DC/DC Converter manufactured by Elite Semiconductor Microelectronics Technology.
ESMT/EMP
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 pensation can reduce external ponent.
The EMD2050 include under-voltage lockout, current limit, over voltage and thermal shutdown protection. The EMD2050 is available in SOT-26 package.
