RECOM introduces a new portfolio of Power ICs and SMD transformers, enabling customers to design their own discrete DC/DC isolated power supplies. The range includes three different topology transformer drivers – flyback, push-pull, and full bridge, integrated and external MOSFET secondary side rectification solutions, and a range of standard sub-miniature SMD transformers that cover the most common input/output and isolation voltages.

The RVPWxxx series flyback power ICs are available with either integrated switches or with a gate drive output for an external MOSFET. These wide input voltage range regulated ICs are unique in having 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 the 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 for minimal board space and are ideal for cost sensitive open loop DC/DC isolated converters. These Power ICs incorporate all the timing circuits and overcurrent monitoring functions for minimum BoM solutions.

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

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

“For over 50 years, RECOM has been a technology leader in DC/DC modules, a position only maintained by a constant flow of new ideas and continual improvements in quality, reliability and performance. Now, for the first time, RECOM is offering you both IC discrete solutions as well as complete DC/DC modules. There is no need for compromise anymore. It is your choice: a standard module that is pre-assembled, tested and ready to go, or a customizable discrete component solution where you decide the layout and component positioning and where you also benefit from lower pricing as the volume increases – just like any other SMD component,” comments Sven Krumpel, Project Manager IC & Solutions, RECOM.
