Description
The Pololu S21Z1F12 generates galvanically isolated 12 V from a wide input range of 5.5 to 36 V. A buck converter, an isolated DC/DC power module (TI UCC33420), and a boost converter are combined on a single board.
Technical specifications:
- Input voltage: 5.5–36 V (operation from approx. 4.6 V with reduced current)
- 12 V output: up to 100 mA
- Additional isolated 5 V output: up to 300 mA (when the 12 V output is unloaded)
- Galvanic isolation via TI UCC33420: 820 VRMS operating voltage
- Efficiency: approx. 40–50%
- Quiescent current: max. 6 mA without load
- No reverse polarity protection
- Terminals on a 2.54 mm grid, input and output grounds separated (GNDI / GNDO)
- Dimensions: 10.2 × 33.0 × 4.3 mm
- Weight: 1.7 g
