PMP30473 – Lowest noise auxiliary dual output (+5 V and -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.
Input filter ensures lowest reflected ripple
Power stage withstands surge voltages up to 42 V
Circuit tolerates cranking down to 4 V
Temperature rise is less than 20 K at full load and with nominal automotive input voltage
