Features

? Uses a synchronous rectification type step-down circuit (ch1, ch2)

? Uses a synchronous rectification type step-up/down circuit (ch3)

? Uses a switching circuit to switch between step-down (using synchronous rectification) and inverting (using asynchronous rectification) (ch4)

? Incorporates a power MOSFET (ch1 to ch3)

? Incorporates a phase compensator (ch1 to ch4)

? Operating frequency: 300 kHz to 1500 kHz

? Can use an external clock (to improve the oscillating frequency accuracy)

? Incorporates a timer-latch-type short-circuit protector

? Incorporates a timer-latch-type overheat protector (shutdown temperature: 150oC or higher)

? Incorporates a recovery-type undervoltage lockout circuit

? Housed in a 48-pin VQFN package
