Synchronous regulators target consumer electronics apps

Phoenix, Ariz.—ON Semiconductor has introduced a new family of high efficiency 2A to 4A integrated synchronous regulators for consumer electronics applications such as set top boxes, DVD/hard disk drives, LCD monitors/TVs, speakerphones, cable modems, and telecom/datacom equipment.

The NCP3125, NCP3126 and NCP3127 are synchronous pulse width modulation (PWM) switching buck regulators with integrated high side and low side MOSFETs capable of delivering continuous output currents of 2A, 3A and 4A respectively.

The devices offer low on-state resistance values [RDS(on)] for integrated switchers resulting in high efficiency system solutions. The NCP3125 has a 60mΩ high-side MOSFET and 36mΩ low-side MOSFET and provides system level efficiencies greater than 90 percent.

All three new devices can produce output voltages as low as 0.8V from an input supply of +5V to +12V. All three devices are pin-to-pin compatible, allowing the flexibility to scale the output current up or down during the product development process or speed up the product development process by allowing quick re-use on new designs. The devices feature an operating junction temperature range of 40°C to +125°C.

The NCP3125, NCP3126, NCP3127 devices are offered in SOIC-8 packages.

Pricing: $0.40, $0.35 and $0.30 per unit in 10,000 unit quantities.
Availability: Now.
Datasheets: NCP3125, NCP3126and NCP3127.
