Description
General part information
TPS56837H Series
The TPS56837H and TPS56837HA are high-efficiency, easy-to-use, synchronous buck converters with wide input voltage range of 4.5V to 28V. The devices support up to 8A continuous output current at output voltages between 4V and 22V, and support 5V, 9V, 15V, 20V dynamic output change for USB Power Delivery (USB PD) application.
The TPS56837H and TPS56837HA use D-CAP3 control mode to provide fast transient response, good line and load regulation, no requirement for external compensation, and support low equivalent series resistance (ESR) output capacitors like MLCC.
The TPS56837H and TPS56837HA operate 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 and TPS56837HA have adjustable soft-start time by the SS pin capacitor configuration.
