Vishay Siliconix
Boost Controller For Double AA Cell or Li-Ion Battery
For White LED Application
DESCRIPTION
SiP12401 is a boost controller IC for double cell NiMH or
Alkaline battery and Li Ion battery, which can drive white
FEATURES
? Voltage Mode Control with Internal
Frequency Compensation
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 600 kHz switching. The voltage-mode PWM
design is internally compensated, reducing the external
parts count. It accepts input voltages from 1.8 V to 5.0 V. The
LED current can be adjusted externally for its brightness
control. SiP12401 features low shutdown current of under
1 μA.
SiP12401 is available in a lead (Pb)-free 6-pin, PowerPAK
