3 Description
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.
