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-Q1). Post regulators (and post filters) ensure ripple free output voltages. Input voltage range covers automotive and industrial applications.
