ON Semiconductor (distributed in Australia by Allyanz) has introduced a family of 2 ampere (A) to 4 A 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 2 A, 3 A and 4 A, respectively.
The devices offer low on-state resistance values for integrated switchers resulting in high efficiency system solutions. The NCP3125 has a 60 mΩ high-side MOSFET and 36 mΩ low-side MOSFET.
According to ON Semiconductor, all three devices can produce output voltages as low as 0.8 V from an input supply of +5 V to +12 V and feature an operating junction temperature range of −40 to 125 degrees Celsius.
