Working Principle

The SCY991351CDR2G operates on a pulse-width modulation (PWM) scheme. It consists of a voltage reference, an error amplifier, an oscillator with different frequency setting, an internal clock divider and a driver with internal radiative immunity. The error amplifier senses the difference between the voltage reference and actual output voltage and drives the power stages accordingly. The frequency of the PWM signal is determined by the frequency setting. The PWM duty cycle is then adjusted based on the results of the error amplifier. The output voltage is adjusted by controlling the PWM duty cycle and therefore controlling the output power. The device also has an integrated shutdown and power-down feature, which enables a low quiescent current and an increased current limit of 5A.
