Working Principle

At the heart of the MPQ2420GF-AEC1-Z is the pulse-width modulation (PWM) controller, which is capable of generating a high current up to 3A and a wide range of adjustable output voltage. The device works in two switching modes - Non-Synchronous and Synchronous. Non-Synchronous mode controls the output voltage by varying the duty cycle of the switching transistor without the use of additional components. The Synchronous mode reduces the power dissipation on a control MOSFET to the minimum by synchronizing the external switching transistor to the internal oscillator in order to reduce the need for additional components. The MPQ2420GF-AEC1-Z also includes a voltage tracking technique to ensure a constant voltage output over a range of load current. The device also includes a soft-start and enable inputs in order to reduce the current surge at start-up and also provide an enable and disable control for the system.
