RT7753GCS Datasheet Pwm Controller

Manufacturer: Richtek

Overview: RT7753GCS PWM Controller for Programmable Power Converter (USBPD).

General Description

The RT7753GCS series is specifically designed to work with controllers, such as RT7202, to provide a total solution for the USB Power Delivery (USB PD) or a programmable power adapter.

This RT7753GCS not only provides a control scheme of high power efficiency, but also gives a very low standby power control below 50mW when under the 5V standby condition.

The RT7753GCS is such a special design to achieve a wide-range of output voltage by utilizing several innovations, including (1) By using the DMAG pin, the RT7753GCS senses the output voltage to adjust the loop gain for system stability, to adjust the threshold voltage of the output over-voltage protection, to protect external devices, and to adjust the current limit to meet Limited Power Source (LPS) safety requirements;

Key Features

  • including Bulk-Capacitor brown-in /brown-out protection, VDD over-voltage protection (VDD OVP), output over-voltage/under-voltage protection (Output OVP/UVP), secondary rectifier short-circuit protection (SRSP), and external over-temperature protection (External OTP); (3) For constant output power regulation, a resistor connected to CS pin can be used to achieve an accurate line compensation across the universal input voltage range; and (4) The RT7753GCS also provides various features to protec.
