Preliminary Data Sheet μPD168807 4-ch Output DC-DC Converter Controller IC Description The μPD168807 is a DC-DC converter controller IC that consists of 3-ch output circuits containing power MOSFET and 1-ch output circuits that can directly drive power MOSFET. 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 Ordering Information Part No. Package Packing style μ PD168807K9-4EG-E1-A 48-pin plastic VQFN Embossed taping R03DS0001EJ0200 Rev.2.00 Mar 18, 2011 |
