EMD2095-PWM Step-Up DC/DC Converter for Backlight


EMD2095-PWM Step-Up DC/DC Converter for Panel Backlight DataSheet

General Description
    The EMD2095 is a highly efficient, step-up DC/DC converter for driving white LEDs. The device can drive up to 9 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 EMD2095 uses current mode and pulse-width modulated (PWM) operation. Its high switching operation frequency of 1.2MHz allows the system to use small inductor, input and output capacitors. An internal compensation circuit can reduce the external component count.
    To safeguard the system, the EMD2095 includes various protection circuits such as under-voltage lockout, current limit, over voltage and thermal shutdown. EMD2095 are available in the tiny packages of SOT-23-6L.
