PMP8531: This design is a current limiter based on a LED driver. It can be used for various applications and changed easily to a different current limit. PMP8531 uses LM3409 buck controller. An excel spreadsheet shows two different configurations (current source or eletrical fuse) and helps the designer to quickly achieve a working design.
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.
