Chip set is smaller for POL converters

10 August 2005 Power Electronics / Power Management

A new 20 V DirectFET MOSFET synchronous buck converter chip set has performance similar to a pair of SO-8 MOSFETs with a 40% size reduction. International Rectifier's IRF6610 and IRF6636 small can DirectFET MOSFET pair chip set is designed for high frequency, point-of-load (POL) designs where size, efficiency and thermal performance are critical design considerations. The IRF6610 features very low gate charge of 10 nC, minimising switching losses for an optimised control FET function, says the company, while the IRF6636 is a versatile DirectFET power MOSFET with 4,5 mΩ device on-resistance and a low gate charge of 18 nC. The latter can be used as either a synchronous FET for 15 A applications when coupled with an IRF6610, or as a control FET when used with the IRF6691 for 35 A per phase, multiphase applications. The IRF6636/IRF6691 chips can enable greater density in applications such as POL modules, replacing as many as four thermally enhanced SO-8 MOSFET devices, says IR.
