The TPS56837H 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 8A continuous output current at output voltages between 4V and 22V, and supports 5V, 9V, 15V, 20V dynamic output change for USB Power Delivery (USB PD) application.
The TPS56837H 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 TPS56837H operates at Eco-mode to attain high efficiency at light load with fixed 500kHz switching frequency and three selectable current limit through MODE pin configuration. The TPS56837H has adjustable soft-start time by the SS pin capacitor configuration.
The TPS56837H 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 TPS56837H 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.
