3 Description

PL8332G is a monolithic 36V, 3.1A step-down switchingconverter. PL8332G integrates a 36V 79mΩ high side anda 36V, 62mΩ low side MOSFETs to provide 3.1Acontinuous load current over a 6.5V to 36V wide operatinginput voltage with 33V input over voltage protection. Peakcurrent mode control provides fast transient responses andcycle-by-cycle current limiting. Programmable soft-startprevents inrush current at power-up.
