General Description

The RT7791 series is specifically designed to work with

controllers, such as the RT7202, to provide a total

solution for USB PD or a programmable power adapter.

The RT7791 can achieve high efficiency, meet safety

standards, and consume less than 50mW of power in a

5V standby condition.

The RT7791 includes several innovations in order to

provide a solution with a wide range of output voltage.

By way of DMAG pin, the RT7791 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.

The RT7791 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). 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.

The RT7791 also provides various features to protect

against any failures occurring at the secondary-side

component, such as the RT7202 or a shunt regulator.

The RT7791 and the RT7202 work together to realize a

robust and safe design to prevent all the potential fault

scenarios, which may arise from versatile and unknown

connections to various devices, cables, plugs and

receptacles.
