com 2-channel switching regulator controller BA9743AFV The BA9743AFV is a 2-channel switching regulator controller that uses a pulse width modulation (PWM) system.
Both channels can be used for DC / DC converter operations including step up, step down, and inverting.
Because the IC is compactly packaged, it is best suited for use as a power supply in portable equipment.
FApplications DC / DC converters in VCRs, notebook computers, etc.
FFeatures 1) Built-in reference voltage current (±1%).
2) Timer latch, short-circuit protection circuit is built in.
3) Circuit to prevent malfunction during low input voltage is built in.
FAbsolute maximum ratings (Ta = 25_C) 4) Built-in reference voltage (2.
505V) output pin.
5) Rest period is adjustable over the whole range of duty ratio.
