A transformer driver IC offers a simple and flexible approach to designing an isolated DC-DC power supply. Maxim's transformer drivers grant system designers greater flexibility by using the winding ratio of an external transformer, which allows the selection of virtually any isolated output voltage.
Typical transformer driver IC application
Maxim's transformer drivers pair with an external transformer to offer a wide selection of power outputs (0.75W to 10W) and power-supply inputs (2.5V to 36V) to address isolated power requirements for a broad array of applications. Various levels of integration and performance are available, so you'll always find the right product at Maxim for your isolated DC-DC design.
