Regulator ICs
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%).
2) Timer-latch, short-circuit protection circuit
3) Miss-operation prevention circuit for low-voltage in-
put.
4) Reference voltage with output (2.5V).
5) Rest period adjustment is possible over the entire
duty range.
Absolute maximum ratings (Ta = 25 C)
Recommended operating conditions (Ta = 25 C)
