NCP1615C2DR2G Application Field and Working Principle

NCP1615C2DR2G is a power factor correction (PFC) device, commonly known as PMIC. It has been specifically designed to deliver high performance and long-term reliability in a wide range of applications, including motor control and present lighting systems.

The NCP1615C2DR2G features a Constant On-Time (COT) control strategy, which is based on primary side sensing. This COT waveform induces optimal transisitor switching, resulting in high input power factor and harmonic current reduction. The device provides high efficiency and a low, stable switching frequency over a wide input voltage/output power range, minimizing EMI and power losses.

The on-chip voltage mode PFC control divides the whole system line in a fast response part and a low response part according to an adjustable system resistance parameter. This parameter defines the level of output current ripple, and the system response to line voltage and load variations. This device also offers additional features such as programmable frequency dithering, external PFC damping and a low power standby mode.

The NCP1615C2DR2G is supplied in a small HTSSOP-D package and its operating temperature range is from -40 to 85ºC. Its lightweight size and low power consumption make it ideal for any PMIC application demanding high efficiency and reliability.

In conclusion, the NCP1615C2DR2G is an ideal Power Factor Correction (PFC) device for any motor control or lighting system application. It features a Constant On-Time (COT) control strategy with an adjustable system resistance parameter, enabling higher efficiency, low power consumption and stability over a wide input voltage/output power range. In addition, it also offers additional features such as programmable frequency dithering, external PFC damping and a low power standby mode.
