3 Description PL8316 is a monolithic 36V, 1A step-down switching regulator. PL8316 integrates a 36V 250mΩ high side and a 36V, 140mΩ low side MOSFETs to provide 1A 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.PL8316 has configurable line drop compensation,configurable charging current limit. CC/CV mode control provides a smooth transition betweenconstant current charging and constant voltage harging stages. Built-in soft-start prevents inrush current at power-up. |
