General Description
The RT7207 is a secondary-side USB Power Delivery (USB
PD) Type-C controller for high-efficiency off-line AC-DC
converters with slim form factor. The RT7207 integrates
an MCU as a policy engine to handle USB PD protocol,
and also integrates a built-in Biphase Mark Coding (BMC)
transceiver for USB PD or other proprietary protocols. An
internal synchronous rectifier controller (SRC) can operate
in both continuous-conduction mode (CCM) and
discontinuous-conduction mode (DCM) even in the
condition of a wide output voltage range of 3.3V to 20V.
Dual operational amplifiers with respectively programmable
reference voltages are included for voltage-loop and currentloop
regulation to provide programmable constant-voltage
(CV) and constant-current (CC) regulation in high precision.
