Working principle

The S-8355K50MC-NBJT2U is designed to use pulse-width modulation (PWM) control to adjust the output voltage. The S-8355K50MC-NBJT2U features a high-speed DC-DC converter to regulate the output voltage. The regulation is done by controlling the amount of time the output voltage is charged and discharged each clock cycle. The cycle time (Hz) is determined by the clock frequency and the amount of time the output voltage is charged is determined by the duty cycle. When the duty cycle is increased, the output voltage will increase and when it is decreased, the output voltage will decrease. The S-8355K50MC-NBJT2U can be used in a variety of applications due to its wide output voltage range, high efficiency, low ripple noise and integrated over-voltage protection circuit. It also offers several additional features to ensure safe and reliable operation including soft start and adjustable UVLO and OVP.
