The January 2006 downgrade of APS by Fitch Ratings was triggered by rejection of the company's surcharge request for recovery of deferred power supply costs, and adoption of PSA provisions by the commission that are less favorable than had been anticipated by Fitch in its previous ratings (See the Fitch press release dated Jan.
With Tri-State's members' fairly rapid load growth averaging 4% per year, partly reflecting the energy and commodity-based industries in certain of the members' service territories, Tri-State has been in the position of playing catch-up with respect to maintaining adequate power supply to meet load requirements.
Design support includes a data sheet, an application note (AN-41), a Reference Design Kit (DAK-93) containing an operational 32 W continuous, 85 W peak, universal input AC-DC power supply and product samples, and the company's power supply design software program, PI Expert(TM).
GreenPoint(TM) is ON Semiconductor's family of high-efficiency power supply reference designs that meet existing or emerging energy efficiency standards.
Like the CRT-TV open reference design the company introduced earlier in the month, this flat-screen television design delivers standby power of less than 1 W, addresses all functional blocks of the power supply and meets international regulations for low standby power dissipation.
We developed, built and fully tested this CRT-TV power supply reference design to further demonstrate ON Semiconductor's ability to help deliver industry-leading power efficient consumer products to the market," said Andy Williams, vice president of ON Semiconductor's Power Conversion Division.
