The NCP1200AD100R2 from ON Semiconductor is a versatile PWM current-mode controller designed for high-performance, low-standby-power, and cost-effective power supply systems. This integrated circuit is a key component in the design of switch-mode power supplies (SMPS) for a wide range of applications, from consumer electronics to industrial equipment.

Key Features

• Frequency Operation: The device operates at a fixed frequency of 100kHz, providing an optimal balance between efficiency and component size, reducing noise and simplifying the design of the EMI filter.
• Current-Mode Control: Its current-mode architecture ensures excellent line and load regulation, fast response times, and easier loop compensation compared to voltage-mode controllers.
• Low Standby Power: The NCP1200AD100R2 includes a built-in brown-out feature and a very low startup current, which contribute to lower standby power consumption, making it suitable for energy-efficient power supplies.
• Auto-Recovery Protection: The device integrates multiple protection features such as short-circuit protection, overvoltage, and undervoltage lockout, with auto-recovery to ensure the power supply's reliability and longevity.
• Adjustable Deadtime: This allows for optimal management of the trade-off between efficiency and EMI performance by adjusting the turn-on and turn-off times of the switching transistors.
