Integrated switching regulators suit power hungry applications
ON Semiconductor has added three new current mode, fixed frequency switching regulators to its portfolio of power management products.
Targeted at compact, high reliability AC/DC switched mode power supplies, the NCP1129, NCP1126, and NCP1124 incorporate an avalanche-rated 650V MOSFET and frequency foldback, along with a skip mode that improves the light load and standby efficiency, meeting the ENERGY STAR EPS 2.0 standard.
The high degree of integration results in minimal external components and reduces the overall BOM cost, making the devices suited to power system designs for household appliances, DVD players and set top boxes.
The NCP1129, NCP1126, and NCP1124 can deliver up to 25W, 15W and 12W respectively and each generate a jittered 65kHz or 100kHz switching frequency, resulting in improved EMI performance.
