PMP30473 – Lowest noise auxiliary dual output (+5 V and -5 V) power supply reference design

https://www.electronics-lab.com/pmp30473-lowest-noise-auxiliary-dual-output-5-v-5-v-power-supply-reference-design/

This reference design is a 2 x 1-W inverting buck-boost converter. The two output voltages (+5 V and -5 V) are produced from one single buck silicon (TPS57160). Post regulators (and post-filters) ensure ripple-free output voltages. The input voltage range covers automotive and industrial applications. Features Input filter ensures lowest reflected ripple Power stage withstands […]
