Compact high density integrated regulators for consumer applications from IR

The new application-specific devices integrate IR’s high performance control ICs optimized with benchmark HEXFET MOSFETs in a compact 5mm x 6mm power QFN package to enable up to 70 percent space savings compared to discrete solutions, while maintaining an equivalent overall total solution cost.

“Because of its high level of integration and small footprint, the SupIRBuck family delivers significant space savings to help reduce overall system costs for consumer applications while offering superior flexibility and efficiency over traditional implementation using discrete components,” said Goran Stojcic, executive director, IR Enterprise Power Applications and Technical Marketing.

The SupIRBuck family of voltage regulators is designed for 4, 7 and 12 amps of output load current at 600 kHz and 6, 9 and 14 amps at 300 kHz respectively. Key features include wide range input of 2.5 V to 21 V and output range of 0.6 V to 12 V, pre-bias start up, a choice of two fixed switching frequencies, hiccup current limit, thermal shutdown and precise output voltage regulation.

The IR380x family’s thermally enhanced packages with slim 0.9mm profile, allow mounting on the back-side of the motherboard for additional space saving and enable no-air flow operation without heat sink below 10 amps.
