DC-DC step-down power module
A versatile, compact, self-contained module. Useful in a myriad of situations to generate a lower, regulated DC voltage output from a higher voltage supply.
This switch-mode unit has much higher efficiency and lower heat dissipation than traditional linear regulator designs.
Wide input voltage range. Regulated output voltage easily and accurately adjustable using multi-turn preset. Solder pad connections.
Possible applications include:
- Internal regulators for projects and equipment.
- Battery charging circuits.
- Car DC power supplies for games, phones etc.
- Solar and charging circuits.
Specifications:
- Size: Approx. 4.2 x 2.1 x 1.4cm
