The NCP1237 is a high-voltage, high-current PWM controller with current mode control, specifically designed for offline SMPS applications. The NCP1237 includes several features which make it an ideal solution for applications such as lighting, motor control, and entertainment systems. Its features include:

• Integrated high-speed MOSFET driver (DRVH)
• Integrated source/sink dual gate drivers (DRVH1/DRVL)
• Integrated high-side/low-side current sensing (ISEN1/ ISEN2)
• Integrated peaks current limit (typical valley current limit)
• Integrated shutdown/ power-on reset /brown out protection
• Integrated high-speed current sensing circuitry
• Integrated phase-lock loop (PLL)
• Integrated start-up circuit

The NCP1237 controller can be configured for a wide range of operating voltages. Additionally, to ensure optimal noise performance, the NCP1237 incorporates an active noise cancellation circuitry, which allows it to reduce power supply noise and power supply ripple.

The NCP1237 includes an adjustable maximum peak current limit that can be used to restrict the peak demand of the power supply. This feature is particularly useful in applications where peak load current is not predictable and where there is a need for an adjustable current limit.

Additionally, the NCP1237 includes a variety of protections that help minimize risk of component or product damages. These protections include thermal shutdown, over current protection, undervoltage lockout, and short circuit protection.

The NCP1237 is optimized for low power consumption. The controller also includes an integrated low power, low noise start-up circuit, which reduces overall power requirements and minimizes noise associated with power-up and power-down.
