3 Description

PL8310D is a monolithic 36V, 1.5A step-downswitching regulator. PL8310D integrates a 36V250mΩ high side and a 36V, 140mΩ low sideMOSFETs to provide 1.5A continuous load currentover a 4.5V to 36V wide operating input voltage with33V input over voltage protection. Peak current modecontrol provides fast transient responses andcycle-by-cycle current limiting.

PL8310D has configurable line drop compensation,configurable charging current limit. CC/CV modecontrol provides a smooth transition betweenconstant current charging and constant voltagecharging stages. Built-in soft-start prevents inrushcurrent at power-up.
