The dc converter is a switching power supply chip that uses the energy storage characteristics of capacitors and inductors to perform high-frequency switching actions through controllable switches to store the input electric energy in the capacitor. When the switch is turned off , the electric energy is then released to the load to provide energy.

What is the dc converter for?
DC/DC converter is a switching power supply chip, which uses the energy storage characteristics of capacitors and inductors to perform high-frequency switching actions through controllable switches (MOSFET, etc.) to store the input electrical energy. In the capacitor (inductor), when the switch is turned off, the electrical energy is released to the load to provide energy. Its output power or voltage capability is related to the duty cycle (the ratio of the switch conduction time to the entire switch cycle). Switching power supplies can be used for both step-up and step-down applications.
DC/DC is a switching power supply chip.
There are two types of DC-DC products we commonly use. One is a charge pump (Charge Pump), and the other is an inductive energy storage DC-DC converter.
Classification
DC/DC converter is a voltage converter that effectively outputs a fixed voltage after converting the input voltage. DC/DC converters are divided into three categories: step-up DC/DC converters, step-down DC/DC converters, and step-down DC/DC converters.
Principle
The output voltage is compared with the reference voltage through the voltage dividing resistor to form a feedback. When the output voltage decreases and is lower than the reference voltage, the comparator output flips and triggers the oscillator circuit to start working. The oscillation circuit outputs a fixed-time pulse to control the conduction of the MOS tube. Otherwise, the MOS tube will be cut off. Where the turn-on is controlled by the oscillator and the turn-off time depends on the load. In this way, the output voltage can be controlled.
