Product details
Overview
RTQ2077SGQW-QT from Richtek USA Inc. is a DC-DC converter plus LDO power-management IC for industrial and automotive applications. The device integrates switching conversion and linear regulation functions to provide compact local power rails in systems requiring robust multi-rail management.
As part of the RTQ2077S-QT product family, RTQ2077SGQW-QT combines DC-DC converter functionality, LDO support, automotive/industrial orientation, WQFN-16L 3x3 packaging, and QT orderable qualification. For engineers reviewing the RTQ2077SGQW-QT datasheet, RTQ2077SGQW-QT pinout, RTQ2077SGQW-QT application, or RTQ2077SGQW-QT equivalent, this device is widely used in automotive control modules, industrial controllers, sensor power systems, embedded power boards, communication electronics, and compact multi-rail regulator designs.
Technical Context
In automotive and industrial embedded systems, RTQ2077SGQW-QT combines efficient DC-DC conversion with LDO regulation so a single IC can support both switching rails and quieter auxiliary supplies.
The WQFN-16L 3x3 package reduces board area for control modules where thermal grounding and compact routing matter. The QT-oriented product family targets higher-reliability industrial or automotive usage compared with commodity consumer rail converters.
RTQ2077SGQW-QT is commonly used when a board needs a Richtek industrial/automotive DC-DC plus LDO PMIC with a 16-pin WQFN footprint and qualified orderable suffix.
Key Specifications
