General Description

SiP12501 is a boost converter IC for single or double cell NiMH or Alkaline battery pack, which can drive white LEDs connected in parallel to provide backlight in hand-held devices.

Designed with an internal low threshold power MOSFET, it is capable of starting up with a low battery voltage of 0.65 V.

For best efficiency performance, the SiP12501 is designed to operate in PWM mode with 600-kHz switching.
