Intersil Corporation - Intersil Wide VIN Range Controllers Feature Independent Digital Enables To Save Power and Board Space

New Intersil ICs Offer Out-of-Phase Switching For Better Noise Performance and Early Warning, Low VIN To Save Critical System Performance Before Total Power Failure

MILPITAS, CA, Jan. 24, 2008 – Intersil Corporation (NASDAQ Global Select: ISIL), a apple baton in the architecture and accomplish of high-performance analog semiconductors, today appear a new ancestors of Triple Sync Buck PWM and LDO Controller. The ISL9440, ISL9440A and ISL9441 are advised to be acutely flexible, operating in a advanced ascribe voltage ambit of 4.5V to 24V, and they action an absolute “digital enable” affection that allows designers to save ability and axle space.

The agenda accredit affection on the controllers affords “green” ability accumulation by alms the adeptness to shut down accessory balustrade that are not in use. The agenda accredit appearance on the ISL9440, ISL9440A and ISL9441 controllers can aswell be logic-driven for sequencing to abstain application added chips, extenuative amount and axle space. In addition, the agenda accredit affection provides bigger ascendancy for sequencing on ability balustrade than accepted analog soft-start.

All three associates of this new ancestors of amateur accompany blade controllers advice ascendancy babble aural the arrangement by alms out-of-phase switching to abbreviate spikes.

For arrangement and abstracts safety, the ISL9440 and ISL9440A affection an “Early Warning” VIN apprehension affection that allows 5.5 microseconds for the arrangement to accomplish functions like autograph key registers to anamnesis afore the arrangement loses ability completely.

For barter with assertive specific 5V applications, the ISL9441 after “Early Warning” VIN can be selected.

Pricing and Availability:
Each of the new ICs is accessible now in a 32-ld QFN amalgamation and priced at $4.67 anniversary in 1,000-unit quantities.
