PL5500 High Efficiency 4-Switch Bidirectional Buck-Boost Controller

PublishTime：2020-07-21

PL5500 is a synchronous 4-switch bidirectional Buck-Boost controller capable of regulating the output voltage at above or below the input voltage. PL5500 operates over a wide input voltage range of 3.6V to 32V (36 V maximum) to support a variety of applications. PL5500 can operate at charger mode for 1, 2, 3,4,5 and 6 cells battery charge.
PL5500 employs Constant ON time control in buck,boost and buck-boost operation modes for superior load and line regulation. The switching frequency could beset 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 at battery discharging mode when OTG is high, which makes PL5500 an excellent option for USB Power Delivery(PD) application. PL5500 provides voltage control loop, constant current loop, thermal regulation loop, battery temperature sensing, which makes it a perfect solution for batter charge management.
