3 Description
PL84052 is a PWM controller, designed for high performance synchronous Buck DC/DC applications PL84052 employs Constant ON time control. Th with input voltages 3.5 V to 32 V (36 V maximum). e switching frequency could be set to 150kHz, 300kHz, 600kHz or 1200kHz based on different resistor value between FREQ pin and GND pin. The device also features a programmable soft-start function and offers all kinds of protection features including cycle-by-cycle current limiting, input under voltage lockout (UVLO), output over voltage protection (OVP), thermal shutdown and output short protection etc. PL84052 provides voltage control loop, constant current loop, and thermal regulation loop.
