10W Dual Isolated Flyback Converter
The GMR10D000 is a 10W dual isolated flyback converter that typically requires rectified AC input. The module uses primary side control to provide two well-regulated outputs with nominal load of up to 10W total. The main devices used in this design are wide-input range nonlinear controller with frequency adjustment and skipping cycles at low loads. GaN devices for primary switch and Schottky diode rectifiers with zero-voltage switching attain high efficiency in the smallest volume of its class.
GMR10D000 module is in production. A variant GMR10D001 that provides +15V instead of the +6V can be made available by contacting Product Support. Other variants are possible, again contact Product Support.

Isolated Triple Output Floating Bias Converter
The GMR10C000, a 5W module, typically requires 22 VDC input, is a flyback converter with 3 isolated outputs. Accompanied with GMR10D000 dual output Bias Power Controller for high power / high voltage applications, it provides all the floating biases for Upper switches and the lower switches. This series is especially suitable for HV sources, even if bipolar, and system design demands stringent control of the fast switching power devices such as GaN, SiC. For IGBTs, module provides enough power for proper turn-Off bias as well.
An outstanding behavior of the control scheme applied is fast transient recovery- expected in its native applications.
