PL84051 Overview
PL84051 integrates a high efficiency synchronous step-down switching regulator, which includes a 40V, 11m Ω high side and a 40V, 13mΩ low side MOSFETs to provide 5A continuous load current over 4.5V to 36V wide operating input voltage. PL84051 employs Constant ON time control. The switching frequency could be set to 150kHz, 300kHz, 600kHz or 1200kHz based on different resistor value between FREQ pin and GND pin.
