PL5501 High Efficiency 4-Switch Buck-Boost Controller
PL5501 employs Constant ON time control in buck, boost and buck-boost operation modes for superior load and line regulation. 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.
VADJ, IADJ pins are used to program output VBUS voltage and output current limit, provides voltage control loop, constant current loop, thermal regulation loop, temperature sensing, which makes PL5501 an excellent option for USB Power Delivery (PD) application.
