RT6150AGQW

Voltage Regulators - DC DC Switching Regulators Overview

The RT6150AGQW is a current mode Buck-Boost DC/DC converter manufactured by Richtek. It operates from input voltages above, below, or equal to the output voltage, making it suitable for single lithium-ion and multi-cell battery applications. The device features a fixed switching frequency of 1 MHz and delivers an output current of 800 mA. It supports an input voltage range of 1.8 V to 5.5 V with an adjustable output voltage between 2.5 V and 5.5 V. Quiescent current in Power Save Mode is 60 μA. The component is housed in a WDFN-10 package (3x3 mm) and operates within a temperature range of -40°C to +85°C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'GQW' corresponds to the WDFN-10L 3x3mm package variant as defined in the official datasheet. Confirm that the ordering part number matches the RT6150A series specifications rather than the RT6150B series, which utilizes a different 2.5x2.5mm package footprint. Ensure compatibility with required humidity sensitivity levels and reflow soldering profiles during procurement validation.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when the input voltage varies significantly around the desired output level, necessitating a Buck-Boost topology. The 1 MHz switching frequency allows for smaller external passive components compared to lower frequency alternatives. Consider the 60 μA quiescent current in Power Save Mode if extended battery operation in portable applications is a primary design constraint.

Voltage Regulators - DC DC Switching Regulators Part Context

The RT6150AGQW belongs to the RT6150 family of synchronous Buck-Boost converters from Richtek. This family is designed to provide efficient power conversion for battery-operated electronics where the battery voltage may drop below or rise above the system rail. The 'A' designation typically indicates the 3x3mm WDFN-10 package variant, distinguishing it from the 'B' variant which uses a smaller 2.5x2.5mm footprint.
