New Product Introduction

NPI Body

Power Integrations InnoSwitch™3-EP 900V integrated MOSFETs

These devices achieve industry-leading efficiencies of up to 90% across line and load conditions, reducing power supply losses and resulting in compact power supplies without heatsinks

The new products include 900 V versions of the flagship InnoSwitch™3-EP IC family, which enable extremely high-efficiency isolated flybacks up to 35 W. 900 V product families feature internal control engines optimized for high efficiency across load to easily meet energy-related products (ErP) limits, and a variety of line and load protection mechanisms to further enhance system robustness and reliability. Devices achieve industry-leading efficiencies of up to 90% across line and load conditions, reducing power supply losses and resulting in compact power supplies without heatsinks.
