3 Description
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
3.6 V to 32 V (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 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 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.
