描述
PL8310D is a monolithic 36V, 1.5A step-down switching regulator. PL8310D integrates a 36V 250mΩ high side and a 36V, 140mΩ low side MOSFETs to provide 1.5A continuous load current over a 4.5V to 36V wide operating input voltage with 33V input over voltage protection. Peak current mode control provides fast transient responses and cycle-by-cycle current limiting.
PL8310D has configurable line drop compensation,configurable charging current limit. CC/CV mode control provides a smooth transition between constant current charging and constant voltage charging stages. Built-in soft-start prevents inrush current at power-up.
