The TPS56A37 is a high-efficiency, easy-to-use, synchronous buck converter with a wide input voltage range 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.

The TPS56A37 operates at Eco-mode to attain high efficiency at light load with fixed 500kHz switching frequency. The TPS56A37 has adjustable soft-start time by connecting the SS capacitor and with default 1.8ms with the SS pin floating.

The TPS56A37 provides complete non-latched OV (overvoltage), UV (undervoltage), OC (overcurrent), OT (overtemperature), and UVLO (undervoltage lockout) protections combined with power-good indicator and output discharge function features.

The TPS56A37 is available in a 10-pin, 3.0mm × 3.0mm HotRod QFN package, and the junction temperature is specified from –40°C to 150°C.
