Working Principle

The TPS60402QDBVRQ1 is a synchronous buck switching regulator and works on the principle of pulse-width modulation (PWM). PWM is essentially a digital-like signal that has two different output states. In one state, the power device is off and no current is consumed by the load. In the other state, the device is turned on and a pulsed voltage is sent down the line and current is supplied to the load. By modulating the width and frequency of the pulses, the load is supplied with a regulated output voltage.

The regulator uses an internal voltage loop to compare the voltages on both the input and output of the device. If the output voltage is different from the target voltage, the loop makes sure that it\'s adjusted accordingly. The loop keeps making adjustments till the output voltage becomes equal to the target voltage.

The output voltage is further monitored using a feedback pin and any detected incorrect conditions are rectified. This feedback pin can be used to measure the power used by the load. The regulator continuously adjusts the output voltage, depending upon the load current.

In the TPS60402QDBVRQ1, the output voltage can be programmed to any level between 0.8 V and 5.0 V, which makes it ideal for applications requiring adjustable output voltages. The regulator is able to deliver an output current of up to 5A. This ensures that the TPS60402QDBVRQ1 can easily handle applications requiring high power.

TPS60402QDBVRQ1 can operate over a wide input voltage range from 4.5 V to 15 V, thereby providing greater flexibility for applications that require wide input voltage ranges. This helps to ensure that the converter operates efficiently even under extreme conditions.
