Description
The Pololu D24Z3F5 combines a step-down converter with an isolated DC/DC power module (TI UCC33420). It provides galvanically isolated 5 V (optionally 5.5 V) from an input voltage of 5.5 to 36 V—for example, to prevent ground loops.
Technical Specifications:
- Input voltage: 5.5–36 V (operates down to approx. 4.6 V with reduced current)
- Output voltage: 5 V (default) or 5.5 V (via SEL pin), ±4%
- Continuous output current: up to 300 mA
- Galvanic isolation via TI UCC33420: 3000 VRMS base isolation, 820 VRMS operating voltage
- Quiescent current: typ. 1–6 mA without load
- Over-temperature protection
- No reverse polarity protection
- 2.54-mm pitch pins, separate input and output grounds (GNDI / GNDO)
- Dimensions: 10.2 × 25.4 × 3.8 mm
- Weight: 0.8 g
