IR expands SupIRBuck high-density regulator line

El Segundo, Calif.—International Rectifier (IR) has expanded its SupIRBuck portfolio of wide input, single output integrated point-of-load (POL) DC-DC voltage regulators with the introduction of the IR380x family for consumer embedded POL applications up to 14 amps.

Size and feature set are optimized for high performance consumer applications including game consoles, desktop PCs, graphics cards, set-top boxes and LCD TVs.

The IR380x application-specific devices integrate IR's control ICs optimized with 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, according to IR.

The SupIRBuck family of voltage regulators is designed for 4, 7 and 12 amps of output load current at 600kHz and 6, 9 and 14 amps at 300kHz 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.

Pricing: Begins at $1.13 each in 10,000-unit quantities.

Availability: Production orders are available immediately.
