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
