USB PD Type-C Controller for SMPS

RT7207

Update Alert Share

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 current-loop regulation to provide programmable constant-voltage (CV) and constant-current (CC) regulation in high precision.

Applications

  • USB PD Type-C Chargers/Adapters for Smart Phones, NBs, Tablets and All Other Electronics.
  • USB PD Extension Cores with Offline AC-DC Converters.
