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.
