DC DC converters are the components that convert electrical energy between different electrical potentials. The most common are the PT4126A converters which provide a high efficient, low noise solution for powering integrated circuits requiring fast transient response. In this article we will discuss the working principle and application field of the PT4126A.

PT4126A Working Principle

The PT4126A is a step-up/step-down DC to DC converter which uses Pulse Width Modulation (PWM) control to obtain an efficient conversion. The principle behind the operation of the PT4126A is that the input voltage, usually supplied from a battery, is modified by varying the duty cycle of the PWM control in order to provide adjustable output voltage. In order to generate the modulated duty cycle, the internal circuitry of the PT4126A includes an input voltage divider and a feedback voltage loop.

The difference between the input voltage and output voltage is determined by the input voltage divider. This divider consists of an adjustable resistor and an internal reference voltage. The feedback voltage loop monitors the output voltage at all times, and adjusts the duty cycle of the PWM signal accordingly.

The PT4126A is also a switching voltage regulator which means it can continuously adjust output voltage and current to regulate output power. This is especially useful for devices that are susceptible to under voltage or overvoltage conditions. On top of all this, the PT4126A also offers several advanced features such as input current limiting, over temperature protection and soft start.
