描述
PL83081 is a PWM controller, designed for high
performance synchronous Buck DC/DC applications
with input voltages 3.0 V to 24 V .
PL83081 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), thermal shutdown and output short protection
etc.
PL83081 provides voltage control loop, constant
current loop, and thermal regulation loop.
