RT6190G

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

Features

General Description

⚫ Integrated Buck-Boost Controller:

 Wide Input Voltage Range: 4.5V to 36V

 Wide Output Voltage Range: 3V to 36V

 Peak Current Mode Control

⚫ Adjustable Soft-Start Time

The RT6190G is a 4-switch Buck-Boost controller

designed for converting input voltage to output voltage

that can be equal to, higher or lower than input voltage.

The RT6190G operates with wide input voltage range

from 4.5V to 36V, and the output voltage can be set from

3V to 36V by external FB pin.

⚫ Power Good Indicator

⚫ Built-in Bleeders for Quick VOUT Discharge

The RT6190G implements peak current mode control

mechanism for smooth operating in Buck, Boost and

Buck-Boost modes. It also features adjustable soft-start

⚫ I C Compatible Interface

 Programmable Switching Frequency (250kHz to

1MHz)

function through external SS pin. With an I C

 Selectable PSM (Default) and FCCM

compatible interface, the RT6190G supports many

programmable functions including switching frequency,

power path control, and CC output without modifying

external current sense resistor. Moreover, the RT6190G

integrates full protection such as input UVLO,

overvoltage/undervoltage protection, cycle-by-cycle

current limit, short protection, and over-temperature

protection.

 AnyPower

for Constant Current (in 9-Bit

Resolution) Output Settings

 Embedded 2 OCP Function

 Power Path Control

⚫ Full Protection with UVLO, OVP, UVP, OCP, Cycle-

by-Cycle Current Limit and OTP

⚫ WQFN-40L 5x5 Package

The RT6190G is available in a WQFN-40L 5x5 package.

Applications

⚫ Buck-Boost Bus Supply

The recommended junction temperature Range is

⚫ Docking Station

−40C to 125C.

⚫ USB Power Delivery
