Description

Mornsun B0503S-1WR3 Isolated DC-DC Converter Module

B0503S-1WR3 isolated DC-DC converter module with 5 V nominal input, 3.3 V unregulated output and 1 W rated power.

The Mornsun B0503S-1WR3 is an isolated DC-DC converter module that converts a nominal 5 VDC input to a single unregulated 3.3 VDC output. It provides up to 1 W of rated output power for designs that need a 5 V to 3.3 V power module with input-output isolation.

Its compact SIP package and industry-standard pinout support straightforward board integration. Continuous, self-recovery short-circuit protection helps the module resume operation after a short is removed. The unregulated output suits circuits that can work with output voltage variation as load and input conditions change.

Use this 1 W isolated converter in pure digital circuits, low-frequency analog circuits, relay-driven circuits or data switching circuits. Isolation can help separate the input and output sides of these systems.
