Dual Constant Current Step-Down Switching Converter
Features
Output voltage using PWM signal or analog signal
Short Protection (OSP), Cycle-by-Cycle Peak Current Limit, thermal regulation, thermal shutdown, input UVLO, output OVP etc.
| Description 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. |
