Instrument Cluster Applications for Automotive (PMP8549)

This reference design supports the supply to power an instrument cluster application using the TPS54260-Q1. The device can handle an input range of 9V to 16V with an output of -6.5V at 400mA due to the inverting buck/boost regulator. It works in continuous conduction mode and a post-filter is optional for this design.


Integrated 200mΩ N-channel FET to produce efficiency greater than 90% peak Pulse skipping eco-mode allows for high light load efficiency Device is optimized for low duty cycle operation or frequency band avoidance Synchronized to external clock to eliminate beat noise Adjustable slow start time to reduce in-rush currents Power good, enable, and track pin to implement various sequencing schemes
