Description

Mornsun B1203S-1WR3 Isolated DC-DC Converter Module

Mornsun B1203S-1WR3 isolated, unregulated DC-DC converter with 12 VDC input, 3.3 VDC output and 1 W rated power.

The Mornsun B1203S-1WR3 is an isolated DC-DC converter that converts a 12 VDC input to a single 3.3 VDC unregulated output. Its 1 W power rating suits low-power designs that need input-to-output isolation.

The isolated design separates the input and output circuits. Continuous, self-recovering short-circuit protection helps the module resume operation after a short is removed. An industry-standard pinout supports integration into circuit boards.

Use this converter for pure digital circuits, low-frequency analog circuits, relay-driven circuits and data switching circuits. Its isolated output can help supply these circuits from a 12 V power rail.
