Working principle of LP3875EMPX-2.5/NOPB

The LP3875EMPX-2.5/NOPB uses a typical switching regulator circuit to convert the input voltage into an output voltage. A power MOSFET is used as the switching element to step down the input voltage. A PWM signal controls the gate of the MOSFET. The MOSFET turns on when the PWM signal is high and off when the PWM signal is low. The PWM signal creates a series of on and off pulses, with each pulse controlling the amount of time the MOSFET is turned on.

The LP3875EMPX-2.5/NOPB also includes a control circuit to adjust the duty cycle of the PWM signal in order to regulate the output voltage. If too much voltage is output, the control circuit reduces the duty cycle of the PWM signal so the MOSFET is turned on less often, which reduces the input power. If the output voltage is too low, the control circuit increases the duty cycle of the PWM signal so the MOSFET is turned on more often, which increases the input power.

The IC also features under-voltage lockout and cycle-by-cycle current limiting functions. Under-voltage lockout ensures that the device does not run when input is lower than its specified minimum level, which prevents damage to the converter circuit and output voltage. Cycle-by-cycle current limiting prevents the MOSFET from being overloaded and damaged. In addition, the LP3875EMPX-2.5/NOPB is also endowed with temperature protection and soft start capabilities.
