RT7755GEK

PWM Controller for Programmable Power Converter (USBPD)

General Description

Features

 Optimized for Adaptive Output Power

 Wide VDD Range : 9V to 64V

 Adaptive Output Over-Voltage Protection

 Adaptive Over-Current Protection

 Adaptive Loop Gain Control for Loop Stability

 High Efficiency

The RT7755GEK series is specifically designed to work

with controllers, such as the RT7206, to provide a total

solution for USB PD or a programmable power adapter.

This RT7755GEK not only provides a high power

efficiency control scheme, but also gives a 50mW very

low standby power control under 5V standby condition.

The RT7755GEK is such a special design to achieve a

wide-range of output voltage by utilizing several

innovations, including (1) By using DMAG pin, the

RT7755GEK senses output voltage to adjust loop gain

for system stability, to adjust output over-voltage

protection threshold voltage to protect external devices,

and to adjust current limit to meet Limited Power Source

(LPS) safety requirements; (2) The RT7755GEK is also

equipped with comprehensive protection 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 accurate

line compensation across the universal input voltage

range; and (4) The RT7755GEK also provides various

features to protect against any failures occurring at the

secondary-side component, such as the RT7206 or a

shunt regulator.

 Green Mode Operation at Light Load and No

Load

 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

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

 Driver Capability : 300mA/300mA

 SmartJitter Technology

Applications

 USB PD and Programmable Power Adapters

In applications, it is suggested that the RT7755GEK be

used with a secondary controller RT7206 to realize a

robust and safe design to prevent all potential fault

conditions due to misconnection of various devices,

cables, plugs and receptacles.
