PWM controllers.Pulse Width Modulator (PWM (Pulse Width Modulation) A modulation technique that generates variable-width pulses to represent the amplitude of an analog input signal. Like its fixed-width pulse density modulation (PDM) cousin, the output switching transistor is on more of the time for a ) Controllers feature integrated EMI (ElectroMagnetic Interference) An electrical disturbance in a system due to natural phenomena, low-frequency waves from electromechanical devices or high-frequency waves (RFI) from chips and other electronic devices. Allowable limits are governed by the FCC. reduction technology for tow noise switched mode power supply (SMPS SMPS Society for Marketing Professional Services SMPS Switching Mode Power Supply SMPS Switched Mode Power Supply ) converter and inverter applications. This family of controllers is designed to replace the184X/384X series PWM controllers in a wide range of switched mode power supply applications, but with the alleged advantage of a built-in EMI reduction engine.
