15W Dual Isolated Flyback Converter Modules
* Smallest off-lineisolated module for effective system level integration, suitable for a wide variety of systems. . Employing primary side control, this module ensures precise regulation of two outputs, effectively handling a load of up to 15W. The key components include a flexible nonlinear controller, allowing adjustable frequency over a wide input range and the ability to skip cycles during lighter loads. This design maximizes efficiency while maintaining a compact form factor. GaN devices enable primary switching, and zero-voltage switching is achieved through Schottky diode rectifiers.
Additionally, alternate versions known as GMR10D004 and GMR10D005 offers a +15V output instead of +6V these modules are currently in production and readily available. These modules implement primary side control to ensure two outputs are well-regulated. The fundamental components employed in this design encompass a wide-input range nonlinear controller offering frequency adjustments and the ability to skip cycles at low loads. These characteristics contribute to the effective and efficient performance of the system. In the GMR10D004 module, the primary switching is facilitated by the Transphorm TP65H480G4JSG GaN device. Similarly, in the GMR10D005 module, the primary switching is managed by the GaN Systems GS-065-011-2-L device.
