The Renesas RAA2116054GP3#JA0 is a 500 mA step-down (buck) switching regulator with an input range of 4.5 V to 60 V. It delivers an adjustable output from 0.8 V up to 57 V.
Non-synchronous topology — design implications
Because the RAA2116054GP3#JA0 does not integrate a synchronous rectifier, the low-side path is handled by an external diode. This adds one BOM component.
Housed in a TSOT-23-6 (thin SOT-23-6) surface-mount package, the part occupies minimal board area.
