RT7786GxV

PWM Controller for Programmable Power Converter (USBPD)

General Description

Features

 Optimized for Adaptive Output Power

 Wide VDD Range : 10V to 32V

 Adaptive Output Over-Voltage Protection

 Adaptive Over-Current Protection

 Adaptive Loop Gain Control for Loop Stability

 High Efficiency

The RT7786GxV series is specifically designed to work

with controllers, such as RT7207, so as to provide a

total solution for the USB PD or the programmable

power adapter. The RT7786GxV is able to achieve the

high efficiency performance, meet safety standards,

and consume low standby power, which is normally

less than 30mW in a 5V standby condition.

 Green Mode Operation at Light Load or No

Load

The RT7786GxV offers several innovative features in

order to provide a solution having the wide-range

output voltages. By using the DMAG pin, the

RT7786GxV senses output voltages to adjust the loop

gain for system stability, to adjust the output

over-voltage protection threshold voltage for external

device protection, and to adjust the current limit to meet

Limited Power Source (LPS) safety requirements.

 Comprehensive Protection Features

 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

The RT7786GxV is also equipped with comprehensive

protection features, including 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). For an application with constant output

power regulation, a resistor connected to CS pin can be

used to achieve the accurate line compensation across

the universal input voltage range. The RT7786GxV

also provides various features to protect against

failures occurring at the secondary-side component,

such as the RT7207 or a shunt regulator.

 < 30mW in 5V Standby Mode for Power Saving

 Driver Capability : 300mA/300mA

 SmartJitter^TMTechnology

Applications

 USB PD

 Programmable Power Adapters

The RT7786GxV and the RT7207 can be used

together to realize a robust and safe design preventing

all potential fault scenarios, due to versatile and

unknown connections of various devices, cables, plugs

and receptacles.
