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.
