TPS56837H Buck Converter Evaluation Module
Description
The TPS56837H is a high-efficiency, easy-to-use,
synchronous buck converter with a wide input voltage
range of 4.5-V to 28-V, and supports up to 8-A
continuous output current at output voltages between
4-V and 22-V for USB Power Delivery (USB PD)
application. The TPS56837H operates at Eco-mode
to attain high efficiency at light load with fixed 500 kHz
switching frequencies and three selectable current
limit through MODE pin configuration. D-CAP3
control mode provides an easy-to-design, stable
regulation with very little external components, and
supports cost-effective ceramic capacitors.
