Two-Channel Regulator IC Guide

The BA9741F and BA9741FS are two-channel switching regulator controllers that use PWM for DC to DC conversion for applications such as video cameras and computers. They feature a high-accuracy reference voltage, short-circuit protection, and allow adjustment of the rest period over the entire duty range. The compact package makes them suitable for portable equipment.

Two-channel switching regulator


controller
BA9741F / BA9741FS

The BA9741F and BA9741FS are two-channel switching regulator controllers that use the PWM method. Both circuits
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.

Applications
DC / DC converters for video cameras and notebook computers etc.

Features
1) High-accuracy reference voltage circuit (±1%). 4) Reference voltage with output (2.5V).
2) Timer-latch, short-circuit protection circuit 5) Rest period adjustment is possible over the entire
3) Miss-operation prevention circuit for low-voltage in- duty range.
