PHOENIX, Ariz. – March 8, 2006 – ON Semiconductor today announced general availability of the NCP1521
600 mA DC-DC stepdown converters, optimized for portable applications powered from one cell Li-ion or three cell alkaline/NiCd/NiMH batteries.
The devices include integrated soft-start, cycle-by-cycle current limiting, and thermal shutdown protection. Automatic switching between PWM and PFM modes provides improved system efficiency. NCP1521 switches at 1.5 MHz, and delivers up to 96 percent efficiency. The NCP1522 switches at 3.0 MHz, and delivers up to 93 percent efficiency. These high frequencies allow use of lower value inductors and output capacitors, which results in a physically smaller subsystem solution.
Both devices are currently in production, and expand ON Semiconductor’s extensive DC-DC switching converter portfolio. They are offered in space-efficient 3 mm x 3 mm TSOP-5 packages. NCP1521 is priced at $0.60 per unit in 3,000-unit quantities. NCP1522 is priced at $0.65 per unit in 3,000-unit quantities. Samples may be ordered at https://www.onsemi.com.
