RT6190G

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

RT6190G
New

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.

The RT6190G implements peak current mode control mechanism for smooth operating in Buck, Boost and Buck-Boost modes. It also features adjustable soft-start function through external SS pin. With an I2C 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.

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

The recommended junction temperature Range is -40°C to 125°C.
