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