PL56002 is a PWM controller, designed for high performance synchronous Buck DC/DC applications
with input voltages 4.2 V to 32 V
PL56002 employs Constant ON time control. The switching frequency could be set to 150kHz,300kHz
based on different resistor value between FREQ pinand 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 prote ction etc.
