SiP12401 Description
SiP12401 is a boost controller IC for double cell NiMH or Alkaline battery and Li Ion battery, which can drive white LEDs connected in series to provide backlight in hand-held devices. Series connection of the LEDs provides identical LED currents resulting in uniform brightness and eliminating the need for ballast resistors. For best efficiency performance, the SiP12401 is designed to operate in PWM mode with...
