  • Circuit Ideas: How to parallel regulator modules for high-current supplies
    It's often necessary to connect pointof- load (POL) dc/dc power supply modules in parallel to get a sufficiently high-current output for applications such as test instruments, blade servers, and so forth. Fully integrated POL power modules have a built-in inductor, power MOSFET, PWM controller
  • ENERGY STAR (R) Compliant - Low Cost LED Dimming
    in a dimmer and provides a gate voltage to the series pass MOSFET. The gate drive of the series MOSFET PWMs the LEDs at their peak current rating. The NSIC2050 Constant Current Regulators provides over current and over voltage protection to the LEDs. The NSI5010 limits the power consumption of the dimmer
