Texas Instruments TPS56A37 10A Synchronous Buck Converter
Texas Instruments TPS56A37 10A Synchronous Buck Converter is an easy-to-use, high-efficiency, 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 a fast transient response, good line and load regulation, and no requirement for external compensation. It supports low equivalent series resistance (ESR) output capacitors like MLCC.
The TPS56A37 operates at Eco-mode to attain high efficiency at light load with a fixed 500kHz switching frequency. The TPS56A37 has an adjustable soft-start time by connecting the SS capacitor with the default 1.8ms and 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 Texas Instruments 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.
