R-78B3.3-2.0 Description

Short technical summary and product information.

The R-78B3.3-2.0 is a high-efficiency switching regulator module from Recom Power, designed to replace traditional 78xx linear regulators. It provides a fixed 3.3V output at up to 2A continuous current from an input voltage range of 4.75V to 32V. With typical efficiency of 92% at minimum input and 86% at maximum input, it requires no heatsink in most applications, reducing space and cost.

 

The module is housed in a 3-SIP package with through-hole mounting, measuring 11.5mm x 8.5mm x 17.5mm. It operates over a temperature range of -40°C to 70°C without derating. Protection features include over-temperature protection (OTP) and short circuit protection (SCP). The switching frequency is 460 kHz, and output ripple and noise is limited to 50 mVp-p maximum.

 

This converter is suitable for industrial and embedded applications where a regulated 3.3V supply is needed from a higher input voltage. Its pin-compatible design allows direct drop-in replacement of linear regulators, offering improved efficiency and reduced heat dissipation.
