Working Principle
The S-8521E19MC-BLET2U uses a pulse width modulation (PWM) technique to control voltage and current regulation. It employs a feedback voltage detection circuit to detect the output voltage and regulate its duty cycle accordingly. When the input voltage is higher than the desired output, the duty cycle of control signal will be small; when the input voltage is lower than the desired output, the duty cycle of control signal will be increased. The S-8521E19MC-BLET2U can also be programmed with the overcurrent protection circuit to protect the load from over current condition. Additionally, it supports programmable power-on/off sequencing, which allows an orderly shut down and power up of the system.
