B0505S-1WR3

The B0505S-1WR3 features an industry-standard SIP package pinout, making it physically and electrically compatible with most 5V to 5V 1W isolated DC-DC converters on the market that follow the same footprint. However, always verify your PCB layout against the provided dimension sheet before replacing an existing component.

If the EVISUN B0505S-1WR3 is unavailable, you can use the "Show similar products" feature on LCSC to find direct replacements. Look for 1W isolated, non-regulated single-output DC-DC converters with a 5V input, 5V output, and a matching SIP packaging (11.7x6mm) from other reputable brands.

This module is ideally suited for distributed power systems requiring electrical isolation from the input supply. Common application scenarios include pure digital circuits, general low-frequency analog circuits, relay driver circuits, and data switching networks where noise reduction or ground-loop elimination is necessary.

The EVISUN B0505S-1WR3 operates within a fixed input voltage range of 4.5V to 5.5V (5V nominal) and provides an isolated, non-regulated 5V single-channel output. It delivers a maximum output current of 200mA (1W power), features an 86% conversion efficiency, and offers an isolation voltage of 1500VDC/min.

When implementing this converter, ensure that the maximum capacitive load does not exceed 2400uF to guarantee a proper startup. Additionally, while the module includes sustained short-circuit protection with automatic fault recovery, it is designed for a fixed voltage input and should operate within its specified -40°C to +105°C temperature range for optimal reliability.
