RT6191A

36V Buck Controller with I²C Interface for USB-PD

General Description

Features

⚫ Support USB-PD 3.0 SPR Mode and 28V of USB-

The RT6191A is a Buck controller designed for USB

power delivery (USB PD). It operates with wide input

voltage range from 4.5V to 36V, and the output voltage

is programmable from 3V to 36V. The RT6191A

implements peak current mode control mechanism with

the programmable constant voltage (CV) and constant

current (CC) output to support USB-PD 3.0 SPR mode

and 28V of USB-PD 3.1 EPR mode. It also has built-in

charge pumps for driving external low-cost N-MOSFETs

PD 3.1 EPR Mode

⚫ Integrated Buck Controller :

 Wide Input Voltage Range : 4.5V to 36V

 Wide Output Voltage Range : 3V to 36V

 Peak Current Mode Control

 Programmable Switching Frequency

(250kHz to 1MHz)

 Power Saving Mode Enables Higher Light Load

Efficiency

to control the power path. With an I C compatible

⚫ AnyPower

for Constant Voltage (12.5mV/step,

interface, the RT6191A supports many programmable

functions including CV/CC output, switching frequency,

and cable voltage drop compensation. Moreover, the

RT6191A integrates full protections including input

UVLO, over/under-voltage protection, cycle-by-cycle

current limit, short protection, and over-temperature

protection. The RT6191A is available in a WQFN-40L

5x5 package.
