EMD2095 Overview
The EMD2095 is a highly efficient, step-up DC/DC converter for driving white LEDs. The device can drive up to 8 serially connected white LEDs from a single Li-Ion battery, or to drive multiple serial and parallel binations with a DC power supply from 2.5V to 5.5V. The EMD2095 uses current mode and pulse-width modulated (PWM) operation.
