power supply (SMPS). There is a wide variety of SMPS topologies and their practical implementations used by PSU manufacturers. However they all use the same basic concepts. This page explains the principals of operation of a switching mode power supply and reviews its main parts and functions....
case, independent of the voltage (as low as 0.6 V)—and across the entire temperature range of the device. It adds internal glitch filtering and hysteresis to each comparator. Its logic inputs can be used to start the power-up sequence, shut down all rails, or perform other functions. ...
Its working principle is divided into two parts: a fixed 5V1.5A regulated power supply circuit and a high-precision high-current voltage stabilizing circuit that can be adjusted continuously from 3 to 15V. The first part's circuit is pretty simple. The C1 electrolytic capacitor filters the...
