RT7202
Highly Integrated USB PD Type-C Controller for SMPS
General Description
The RT7202 is a secondary-side USB Power Delivery (USB
PD) Type-C controller for high-efficiency off-line AC-DC
converters. The RT7202 integrates an MCU as a policy
manager to handle USB PD protocol, and also integrates
a built-in Biphase Mark Coding (BMC) transceiver for USB
PD or other proprietary protocols. A programmable
reference voltage for an operational amplifier is included
for voltage-loop regulation to achieve programmable
constant-voltage (CV) regulation in high precision.
