PL8310D 36V, 1.5A Monolithic Step-Down Switching Regulator
1 Description
PL8310D is a monolithic 36V, 1.5A step-downswitching regulator. PL8310D integrates a 36V 250mΩhigh side and a 36V, 140mΩ low side MOSFETs toprovide 1.5A continuous load current over a 4.5V to36V wide operating input voltage with 33V input overvoltage protection. Peak current mode controlprovides fast transient responses and cycle-by-cyclecurrent limiting.
PL8310D has configurable line drop compensation,configurable charging current limit. CC/CV modecontrol provides a smooth transition between
constant current charging and constant voltagecharging stages. Built-in soft-start prevents inrushcurrent at power-up.
