3、Description

PL56001 is a PWM controller, designed for high performance synchronous Buck DC/DC applications with input voltages 4.5 V to 32 V (36 V maximum). PL56001 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. 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), input Over Voltage Protection, thermal shutdown and output short protection etc. PL56001 provides voltage control loop, constant current loop, and thermal regulation loop.
