RT6179

36V, 4-Switch Buck-Boost Controller with I²C Interface

General Description

Features

⚫ Support USB-PD 3.0 SPR Mode and 28V of 3.1

The RT6179 is a 4-switch Buck-Boost controller

designed for USB power delivery (USB PD). It operates

with wide input voltage range from 4.5V to 36V, and the

output voltage can be programmable between 3V and

36V. The RT6179 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 3.1 EPR

EPR Mode

⚫ Integrated Buck-Boost 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

mode. With an I C compatible interface, the RT6179

Efficiency

supports many programmable functions including

CV/CC output, switching frequency, and cable voltage

drop compensation. Moreover, the RT6179 integrates

fully protection such as input UVLO, over/undervoltage

protection, cycle-by-cycle current limit, short protection,

and over-temperature protection. The RT6179 is

available in a WQFN-40L 5x5 package.

⚫ AnyPower

for Constant Voltage (12.5mV/step,

Typ.) and Constant Current (in 9-Bit Resolution)

Output Settings

⚫ I C Compatible Interface

⚫ Adjustable Soft-Start Time

⚫ Programmable Cable Voltage Drop Compensation

⚫ Built-in Bleeders for Quick VOUT Discharge

⚫ Power Good Indicator

Applications
