The TPS61241YFFR integrated buck converter works by using a converter topology, where a switching converter is used to regulate the output voltage. The working principle of the device involves three stages – input rectification, voltage regulation, and output conditioning. The input power is rectified and filtered to produce a DC voltage, which is then compared to the output voltage through a feedback loop. The feedback loop is used to control the switching of the converter’s MOSFETs, thus producing the desired output voltage. The output stages are used to regulate the output current and reduce the ripple. The output is then regulated by the feedback loop, which is controlled by the external clock. This enables the voltage regulation to be done in a very efficient manner, with fast response time to load changes.
