TPS56A37 Step-Down Converter Evaluation Module
Description
The TPS56A37 is a high efficiency, high-voltage input,
easy-to-use synchronous buck converter. With the
wide operating input voltage range of 4.5 V to 28 V,
the TPS56A37 is designed for systems powered from
12-V, 19-V, 24-V power-bus rails. The device supports
up to 10-A continuous output current. The output
voltage range is from 0.6 V to 13 V. DCAP3™ control
mode provides an easy-to-design, stable regulation
with very little external components, and supports
cost-effective ceramic capacitors.
