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.
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.
Features „ WLEDs supports (20mA for each channel): „ Up to 3S13P at VIN=3.
7V „ Up to 3S18P at VIN=5.
0V (Note: SÆ Series; PÆ Parallel) „ Low Quiescent Current: 55 μA „ Over Voltage Protection: 15V „ Inherently Matched LED Current „ Shutdown Current < 1μA „ Reference Voltage 0.
235V „ Efficiency : 85% (Typ) at VIN=5.
0V „ PWM Dimming Control „ In...
