EMD2055 Datasheet | Elite Semiconductor Microelectronics Technology

ESMT PWM Step-Up DC/DC Converter for Panel Backlight (10 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 10 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 EMD2055 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 pensation circuit can reduce the external ponent count. To safeguard the system, the EMD2055 includes various...
