Overview
ESMT/EMP Preliminary EMD2055 PWM Step-Up DC/DC Converter for Panel Backlight (11 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 11 serially connected white LEDs from a single Li-Ion battery, or to drive multiple serial and parallel combinations with a DC power supply from 2.
5V to 5.
5V.
The EMD2055 uses current mode and pulse-width modulated (PWM) operation.
Its high switching operation frequency of 1.
0MHz allows the system to use small inductor, input and output capacitors.
An internal compensation circuit can reduce the external component count.
