RB-3.305S Description

Short technical summary and product information.

The RB-3.305S is part of Recom Power's RB series of low-cost, isolated DC/DC converters. This 1W device provides a regulated 5V output from a nominal 3.3V input with a maximum output current of 200mA. Typical efficiency is 78% at full load and 25°C ambient.

 

The converter offers 1kVDC input-to-output isolation (tested for 1 second) and operates with a nominal switching frequency of 100kHz. Output ripple and noise are limited to 100mVp-p maximum (20MHz bandwidth). It requires no minimum load and includes basic short circuit protection (SCP). The input voltage range is ±10% around the 3.3V nominal.

 

Packaged in a compact 7-SIP module with 5 leads, the RB-3.305S is designed for through-hole mounting. Its dimensions are 19.7mm x 6.0mm x 10.2mm. The operating ambient temperature range is -40°C to +85°C. The module is UL60950-1, CAN/CSA-C22.2 60950-1, and IEC/EN60950-1 certified, and EN55032 compliant for commercial ITE applications.
