Overview
The RT6190GQW is a 36V, 4-Switch Bidirectional Buck-Boost Controller manufactured by Richtek. It features an I2C interface and supports three outputs with adjustable voltage ranging from 3 V to 36 V. The device operates at a switching frequency between 250 kHz and 1 MHz, with a maximum duty cycle of 50%. It provides an output current capability of 2 mA and functions within a temperature range of -40 C to +125 C. The component is housed in a WQFN-40 package.
Feature Summary
- Supports bidirectional buck-boost topology for flexible power conversion
- Includes integrated I2C interface for digital control and monitoring
- Provides three independent output channels
Applications
- Systems requiring bidirectional energy flow management
- Applications utilizing I2C-based digital control architectures
- Multi-output power supply designs operating within specified voltage ranges
Procurement Notes
Verify the specific suffix against official datasheets to confirm pinout and thermal characteristics. Ensure compatibility with I2C bus requirements and check moisture sensitivity levels before assembly. Confirm that the WQFN-40 package aligns with PCB layout constraints and thermal dissipation needs for the intended operating environment.
Selection Notes
Select this controller when a bidirectional buck-boost solution with digital I2C control is required. Consider the 36V input/output limits and the 250 kHz to 1 MHz frequency range. Verify that the WQFN-40 package fits the design space and that the -40 C to +125 C operating temperature meets environmental specifications.
Part Context
This component belongs to the Richtek PMIC family, specifically designed as a switching controller. It integrates four switches to enable bidirectional power flow, distinguishing it from standard unidirectional regulators. The inclusion of an I2C interface allows for precise configuration and status monitoring in complex power systems.
