3 Description
PL8310E is a monolithic 36V, 1A step-down
switching regulator. PL8310E 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.
PL8310E 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.
