DC / DC converter is a switching power supply chip. It refers to the use of the energy storage characteristics of capacitors and inductors, and performs high-frequency switching through a controllable switch (MOSFET, etc.). When disconnected, 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 on-time of the switch to the period of the entire switch). Switching power supplies can be used for step-up and step-down.
A 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-up and step-down DC / DC converters.
