ON Semiconductor Introduces µCool™ Portfolio of Power MOSFETs for Portable Applications

PHOENIX, Ariz. – Recognizing the industry’s need for smaller, thinner, faster, cooler running and more reliable MOSFET devices for portable applications, ON Semiconductor (Nasdaq: ONNN) today introduced µCool™ (micro-cool) - a new family of power MOSFETS that deliver leading edge performance and design flexibility for portable applications. This introduction is marked by the release of the company’s first six uCool™ devices in a thermally-enhanced, remarkably small, WDFN6 package.

“We have designed the µCool™ portfolio to exclusively address the unique power management challenges in portable devices such as lithium-ion battery charging circuits, high and low side load switches, and synchronous buck and boost circuits,” said Thibault Kassir, ON Semiconductor’s director of marketing for Power MOSFETS. “These first µCool™ devices are just the beginning of what we expect will be an extensive portfolio utilizing our latest trench technology. Operating voltages will range from 8 V to 30 V and a variety of configurations will be offered - including single, dual, FETKY® complementary and integrated load switch.”

The six debut µCool™ products utilize exposed drain DFN technology for exceptional thermal resistance (38° C/W) and power ratings (1.9 W) in an impressively small 4 mm square footprint. Delivering up to a 190 percent improvement in steady state power rating over the industry standard SC-88 package and 130 percent improvement over the SC-70-6 flat lead package, the WDFN6-packaged µCool™ devices - from a power perspective - make significantly better use of valuable board space in portable applications.

The Devices
• The 20 V P-Channel Single NTLJS3113PT1G and the dual NTLJD3115PT1G are both optimized for lithium-ion battery charging applications with RDS(on) at 4.5 V of 42 mohms and 100 mohms respectively. These devices are priced at $0.30 and $0.31 per unit in 10,000 unit quantities.
• The 20 V P-Channel FETKY® NTLJF3117PT1G (100mohms) is optimized to convert the 3 V to 4 V battery voltage into 1.1 V to power the microprocessor. This device is priced at $0.31 per unit in 10,000 unit quantities
• The 30 V N-Channel Single NTLJS4159NT1G (35 mohms) and FETKY® NTLJF4156NT1G (70 mohms) are both optimized for synchronous boost applications such as white LED backlight voltage. These devices are priced at $0.29 and $0.30 per unit in 10,000 unit quantities
• The 30 V N-Channel dual NTLJD4116NT1G (70 mohms) is optimized for low side switching such as camera strobe and flash. This device is priced at $0.30 per unit in 10,000 unit quantities

While the new µCool™ power MOSFET family have the same footprint dimensions as a standard SC-88 and SC-70-6 packages, ON Semiconductor’s latest MOSFETs offer the added feature of an exposed flag on the bottom surface that acts as a drain contact and heat dissipation path. The improved thermal path allows for either greater power handling or operation at a lower junction temperature. These options are important in battery operated devices because lower junction temperature equates to lower RDS(on) or less power loss. This, in turn, extends the life time of the battery – an extremely important factor considering the many power-draining features being designed into cell phones, digital still cameras, portable games, portable global positioning systems or just about any consumer electronic battery powered system.

“The µCool™ product portfolio hits the mark within the portable industry for size, thermal resistance and power rating – especially when compared to larger packages such as the Micro-8, TSOP-6 and ChipFET,” said Tom Zemites, ON Semiconductor’s product marketing manager for Portable MOSFET Products. “We are providing the industry with a smaller power package that will enable designers to dramatically reduce board space without sacrificing performance, all in a non-bump form.”
