BA9744FV
The BA9744FV is a 2-channel switching regulator controller that uses the PWM method.
Both circuits can be used for DC / DC conversion for step-up, step-down, and inverting. The IC comes in an extremely
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-
put.
4) Reference voltage with output (1.222V).
5) Reset period adjustment is possible over the entire
duty range.
FAbsolute maximum ratings (Ta = 25_C)
FRecommended operating conditions (Ta = 25_C)
