RT7752

PWM Controller for Programmable Power Converter (USBPD)

General Description

Features

 Optimized for Adaptive Output Power

 Wide VDD Range : 10V to 40V

 Adaptive Output Over-Voltage Protection

 Adaptive Over-Current Protection

 Adaptive Loop Gain Control for Loop Stability

 High Efficiency

The RT7752 series is specifically designed to work with

controllers, such as RT7202, to provide a total solution

for USB PD or a programmable power adapter. The

RT7752 can achieve high efficiency, meet safety

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

5V standby condition.

The RT7752 includes several innovations in order to

provide a solution with a wide range of output voltage.

By way of DMAG pin, the RT7752 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.

 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

The RT7752 is also equipped with comprehensive

protection features, including Bulk-Capacitor brown-in

/brown-out protection, VDD over-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). 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 RT7752 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

The RT7752 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.
