NCP53 Series PWM Controllers for CPU VRM Applications

The NCP53 Series from onsemi (ON Semiconductor) is a well-known family of high-performance PWM controller ICs designed specifically for CPU and GPU VRM (Voltage Regulator Module) applications. These ICs are widely used in laptop and desktop motherboards to deliver accurate voltage regulation, fast transient response, and high efficiency required by modern processors.

The NCP53 series supports single-phase to multi-phase (up to 4-phase) synchronous buck architectures, depending on the model. Many variants include advanced features such as adaptive voltage positioning (AVP), differential voltage/current sensing, dual-edge PWM modulation, phase balancing, and integrated protection functions. This makes the series suitable for both Intel and AMD platform power requirements.Buy NCP5359, NCP5380, NCP5387, NCP5388, NCP5391, and NCP5392T PWM Controller ICs from OKSpare Nehru Place Delhi for reliable CPU VRM power IC
