RT7753GCV

PWM Controller for Programmable Power Converter (USBPD)

General Description

Features

 Optimized for Adaptive Output Power

 Wide VDD Range : 9V to 42V

 Adaptive Output Over-Voltage Protection

 Adaptive Over-Current Protection

 Adaptive Loop Gain Control for Loop Stability

 High Efficiency

The RT7753GCV 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 RT7753GCV 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.

 Green Mode Operation at Light Load and No

Load

The RT7753GCV 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

RT7753GCV 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; (2)

The RT7753GCV is also equipped with comprehensive

protection features, including Bulk-Capacitor brown-in

/brown-out protection, VDD over-voltage protection

 Comprehensive Protection Features

 Bulk-Capacitor Brown-In and Brown-Out

Protection

 VDD Over-Voltage Protection

 Output Over-Voltage and Under-Voltage

Protection

 External Over-Temperature Protection

 Secondary Rectifier Short-Circuit Protection

 Programmable Line Compensation

 Others

(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 RT7753GCV also provides various

features to protect against any failures occurring at the

secondary-side component, such as the RT7202 or a

shunt regulator.

 < 50mW in 5V Standby Mode for Power Saving

 Driver Capability : 300mA/300mA

 SmartJitter^TMTechnology

Applications

 USB PD and Programmable Power Adapters

In applications, the RT7753GCV is suggested to use

with a secondary controller RT7202 to realize a robust

and safe design so as to prevent all potential fault

conditions due to misconnection of various devices,

cables, plugs or receptacles.
