S-1711B2828-M6T1G Working Principle

S-1711B2828-M6T1G works on a basic switch-mode power supply design principle. A switch is periodically opened and closed, which in turn turns the voltage regulator on and off. This process is known as pulse width modulation, or PWM. During the "on" phase, the energy stored in the inductor gets converted into output voltage. During the "off" phase, the energy stored in the capacitor is used to maintain the output voltage.

The PWM frequency is usually set with an external resistor and capacitor. The duty cycle of the pulse width modulation is also adjustable depending on the load current. S-1711B2828-M6T1G has a built-in current limiter, which reduces the output voltage when the current reaches the pre-set threshold. It also has an adjustable soft-start feature which prevents the inrush current at startup, allowing a smooth and stable start-up.

S-1711B2828-M6T1G also includes many protection features such as over-current protection, over-temperature protection, and under-voltage lockout. These features secure devices from damage due to abnormal conditions.
