The RT7207K is a programmable controller with integrated synchronous rectification control. Its internal MCU handles various proprietary protocols via the D+/D- interface and supports USB PD Type-C via the CC1/CC2 pins.
The RT7207K provides high integration for high power density off-line AC-DC converter designs. In addition to saving external components, and through the built-in synchronous rectification controller and integration of diverse functions and protections, it not only improves efficiency but also enhances safety.
An internal synchronous rectifier controller can optimize efficiency and provide safe operate in both continuous-conduction mode (CCM) and discontinuous-conduction mode (DCM) even in the condition of a wide output voltage range of 3.0V to 21V.
Dual operational amplifiers with respectively the digital-to-analog converter (DAC) 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.
