Working Principle

The ALO12A48N-S converts a higher voltage input into a lower voltage output with a fixed output voltage. It operates using a current-mode switching regulator topology. The device consists of a power switch, an oscillator, an error amplifier, an output voltage feedback, and an output current sense. The power switch, oscillator, and error amplifier form the control loop. The input voltage is regulated by the oscillator with the use of the error amplifier. The output voltage is fed back to the error amplifier which compares the output voltage to the reference voltage. If there is a difference, the error amplifier adjusts the output voltage by changing the current flow through the power switch. This process is repeated until the output voltage is stabilized. This is the basic working principle of the ALO12A48N-S.
