Texas Instruments TPS56A37 | Demoboard TPS56A37

Beschreibung

The TPS56A37 is a high-efficiency, easy-to-use, synchronous buck converter with a wide input voltagerange of 4.5V to 28V. The device supports up to 10A continuous output current at output voltages between 0.6V and 13V.The TPS56A37 uses D-CAP3 control mode to provide fast transient response, good line and load regulation, no requirement for external compensation, and supports low equivalent series resistance (ESR) output capacitors like MLCC.
