IR3842AMTRPBF Application Field and Working Principle

IR3842AMTRPBF is a synchronous buck voltage regulator which falls under the category of DC DC switching regulators and is manufactured by various semiconductor companies, including International Rectifier Corporation. The device is optimized specifically to provide a high efficiency and low ripple output with an adjustable output voltage. This voltage regulator is suitable for a wide range of applications which involve powering of high-density point of load Pol applications, such as electric vehicles and consumer electronics.

The working principle of this voltage regulator involves the use of a buck converter which is used to step-down the input voltage source. The voltage source is then regulated by an error amplifier in order to maintain a constant output voltage. The output voltage of the regulator can be adjusted by changing the feedback voltage via a voltage divider. The error amplifier then provides a feedback signal to the internal power MOSFETs which control the switching of the power stage.

The IR3842AMTRPBF voltage regulator has an input voltage range of 3.2V to 22V and an output voltage range of 0.8V to 17V. It features a fast transient response and a low output noise of 1.3mV (peak-to-peak). The device also features built in over-temperature and under-voltage protection.
