Two MOSFETs lower power consumption with 4.5V logic level drive
PCIM Europe 2017 Stand 9-301 Toshiba has announced two 100V N-channel power MOSFETs, that feature a lower power consumption, due to 4.5V logic level drive, for quick chargers, switched mode power supplies and DC/DC converters.
The latest additions to the company’s U-MOS VIII-H series are low-voltage N-channel power MOSFETs. The TPH6R30ANL and TPH4R10ANL support the quick charger 4.5V logic level drive and are suitable for use in quick chargers, switched-mode power supplies and DC/DC converters.
The MOSFETs use the company’s low-voltage trench structure process to achieve industry-leading on-resistance and high-speed performance, for use in secondary-side rectifiers.
The semiconductor structure improves the fundamental figure of merit (FoM) (RDS(ON) * Qsw or gate switch charge) for switching applications. Output losses are improved, says the company, by the reduction of output charge, contributing to higher system efficiency.
The TPH6R30ANL offers current handling (ID) up to 45A and RDS(ON) as low as 6.3mΩ while the TPH4R10ANL is rated at 70A and 4.1mΩ.
Support for 4.5V logic level drive enables buffer-less drive from the controller IC, reducing power consumption. The MOSFETs are compatible with the high output voltage power supplies required in USB 3.0 related applications, points out the company, adding that the standard 5.0 x 6.0mm package SOP-Advance will help reduce PCB space.
Both devices are available for immediate shipment.
