Description
The SC4502/SC4502H is a high-frequency current-mode step-up switching regulator with an integrated 1.4A
power transistor. Its high switching frequency (program mable up to 2MHz) allows the use of tiny surface-mount
external passive components.
FEATUREs
Low saturation voltage switch: 210mV (250mV for the SC4502H)
Constant switching frequency current-mode control
Programmable switching frequency up to 2MHz
Soft-Start function
Input voltage ranges from 1.4V to 16V
Output voltage up to 32V (40V for the SC4502H)
Low shutdown current
Adjustable undervoltage lockout threshold
Small low-profile thermally enhanced lead free package. This product is fully WEEE and RoHS compliant.
APPLICATIONs
Flat screen LCD bias supplies
TFT bias supplies
XDSL power supplies
Medical equipment
Digital video cameras
Portables devices
White LED power supplies
