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.
FApplications
DC / DC converters for video cameras and notebook computers etc.
FFeatures
1) High-accuracy reference voltage circuit ( 1%).
2) Timer-latch, short-circuit protection circuit
3) Miss-operation prevention circuit for low-voltage in-
