Dual FETKY co-packaged device offers space savings

6 November 2002 Power Electronics / Power Management

International Rectifier has introduced the IRF7335D1 Dual FETKY device, which co-packages two N-channel MOSTFETs and a Schottky diode in a single SO-14 package. The device is claimed to have the highest current carrying capability among dual MOSFET-Schottky co-packaged offerings today, and delivers 40% more current when compared to IR's previously released IRF7901D1 device.

The IRF7335D1 offers as much as 60% space-savings compared to a similar discrete circuit solution. It is designed for standard 12 V-input, 5 V, 3,3 V and 1,7 V-output synchronous buck converter circuits delivering up to 11 A in notebook and desktop computers, game consoles and Internet appliances. Co-packaging simplifies layout, reduces packaging and assembly cost, increases power density and simplifies procurement logistics according to the manufacturer.

The two MOSFETs in the IRF7335D1 are individually optimised for control and synchronous switching functions. The synchronous MOSFET has low on-resistance for reduced conduction losses. The control MOSFET features low total gate charge and gate-to-drain charge for reduced switching losses and is rated at 30 V breakdown to safely handle input voltage spikes. The internal Schottky diode has low forward voltage drop for fast and efficient switching.
