Overview
UTC BA9741A LINEAR INTEGRATED CIRCUIT TWO-CHANNEL SWITCHING REGULATOR CONTORLLER DESCRIPTION The UTC BA9741A is a two-channel switching regulator controllers that use the PWM method.
It can be used for DC to DC conversion for step-up, step-down, and inverting.
The IC comes in a compact package, making it ideal for use in portable equipment.
SOP-16 FEATURES *High-accuracy reference voltage circuit (±1%).
*Time-latch, short-circuit protection circuit.
*Miss-operation prevention circuit for low-voltage input *Reference voltage with output (2.
5V) *Rest period adjustment is possible over the entire duty *range.
TSSOP-16 APPLICATION *DC/DC converters for video cameras and notebook computers etc.
