onsemi 7-Pin SOIC 5-Channel Current Mode PWM Controller, 65 kHz, 28V, 14V Output, 500mA Output Current NCP12400CBAAB0DR2G

onsemi NCP12400CBAAB0DR2G is a 7-pin SOIC package 5-channel PWM controller designed for power management applications requiring precise current mode control. This device operates at a fixed frequency of 65 kHz and supports a maximum supply voltage up to 28 V, delivering an output voltage of 14 V and output current up to 500 mA per channel.

Engineered with a flyback topology, the NCP12400 incorporates advanced features like Dynamic Self-Supply, which simplifies auxiliary supply design by activating an internal startup current source during power-up, transients, and standby modes. It also includes a special high-voltage detector to detect AC input unplug events and brown-out conditions, enhancing system reliability.

The PWM controller offers an adjustable compensation network and timer-based fault detection to ensure overload protection and maintain maximum power independent of input voltage variations. Its maximum duty cycle of 85% enables highly efficient power conversion, meeting CoC Tier 2 compliance for average efficiency.

With a compact size of 5 mm by 4 mm with a 1.5 mm profile, this surface mount device is suitable for space-constrained industrial, consumer electronics, and power supply manufacturing applications. The robust design supports operation in extreme temperatures from -40°C to 150°C, making it ideal for automotive and industrial environments.
