Working Principles

The 70V631S12BF8 is a voltage regulator IC that converts an input voltage within the range of 4.5V to 70V into a regulated output voltage between 1.2V and 60V. It utilizes a control loop to maintain the desired output voltage by adjusting the duty cycle of an internal switch. The feedback voltage from the output is compared with a reference voltage, and any deviation is corrected by adjusting the switch's on/off time. This continuous regulation ensures a stable output voltage despite variations in the input voltage or load conditions.
