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.
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.
APPLICATION
*DC/DC converters for video cameras and notebook
computers etc.
