Voltage Controllers

Voltage controllers are electronic devices which help to keep a consistent voltage within a circuit. They are commonly used in electronic devices and are designed to help provide voltage management.

They are similar to Voltage regulators in that they control the voltage output. However, voltage controllers are able to create different outputs, such as a variable voltage, or they may act as a switch to divert the power. Voltage controllers convert a fixed voltage input to have variable voltage in output delivered to a resistive load. Similar to voltage converters, voltage controllers include all of the controlling circuitry, but do not include the passive components.

Voltage controllers have a current conversion type, which is AC-DC or DC-DC. AC-DC takes an AC power input and converts it to a DC output voltage.

Types of Voltage Controller:

  • Boost Controller
  • Buck Controller
  • Flyback Controller
  • PWM Controller
  • Step-Down Voltage Controller

Voltage controllers are ICs which come in a semiconductor package. This includes TSSOP, SOIC, SOT-23 and QFN.

Where are voltage controllers used?

Voltage controllers are often used to help drive MOSFETs. They are used in most applications which require power, and some form of voltage management. For example, battery powered devices, power supply units (PSUs) or chargers, computers, automotive and telecommunications.
