IncThe GS9238TQ-R with DC-DC Converters TQFN23-4x4 RoHS is a 4x4-pin TQFN RoHS compliant DC-DC converter manufactured by Green Solution Technology Inc. It is an integrated, highly-efficient, low-input voltage (3.0V-12V), wide-output voltage (1.0V-20V) buck-boost controller that supports multiple topologies, including step-up,step-down,flyback and the single switch Buck-Boost topology. It is designed for applications where high-efficiency is necessary to reduce thermal losses, and the 4x4-pin TQFN RoHS compliant package provides excellent thermal characteristics. The controller also features a low quiescent current (ISD<3µA), excellent current mode control characteristics and fast transient performance. It is highly integrated, cost-efficient and easy to use.
