The RVPWxxx series flyback power ICs are available with integrated switches or with a gate driver output for an external MOSFET. These wide-input-voltage regulated ICs are special because they have three different feedback modes on the same pin: primary-side regulation, where the output is regulated by monitoring the primary-side waveform to avoid the need for an optocoupler; secondary-side regulation, where the output is regulated by optocoupler feedback to maintain isolation; or direct DC monitoring for non-isolated applications.

The RVPxxx push-pull and full-bridge transformer drivers are available in compact DFN2*2 packages to minimize board space and are ideal for open-loop isolated DC/DC converters where cost is a critical factor. These power ICs incorporate all the necessary timing circuitry and overcurrent monitoring functions for minimal BoM solutions.

The core of any isolated DC/DC converter is the transformer, so RECOM offers a standard range of SMD transformers with isolation ratings from 1.5 kVDC/min to 5 kVAC/min to cover the most common input/output voltage combinations. Custom transformers can be supplied to individual specifications within 20 days (minimum order applies).

RECOM also offers the RVSxxx range of secondary-side rectification solutions, which includes a fully integrated full-bridge rectifier IC in a DFN2*2 package, a self-powered external MOSFET rectifier solution that can operate on both the high and low sides, and a bidirectional integrated rectifier designed for charging/discharging battery cells.

“For over 50 years, RECOM has been a technology leader in DC/DC modules, a position maintained only through a constant flow of new ideas and continuous improvements in quality, reliability, and performance. Now, for the first time, RECOM is offering both discrete integrated circuit solutions and complete DC/DC modules. You can choose between a pre-assembled, tested, and ready-to-use standard module or a customizable discrete component solution that allows you to decide on the layout and placement of components and also offers lower prices as volume increases, just like any other SMD component,” says Sven Krumpel, Integrated Circuits and Solutions Project Manager at RECOM.
