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.
