basicInfoDescription
basicInfoImageSwitcher
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.
