How to adjust the output voltage of a power supply?
The external voltage for adjusting the output voltage of the power supply can be generated in several ways. Most commonly a smoothened PWM signal or the output of a digital-to-analog converter (DAC) is used as shown in Figure 2. The first method is often used because it’s very simple and inexpensive.
What does trimming a power supply mean?
Trimming the output voltage of a power supply simply means adjusting the voltage by a small amount. By convention, the term trimming is used for applications where the power supply has a specified nominal output voltage and the user is able to change the output voltage by about ten percent or less.
How does a power supply work?
The power supply design team provides a pin connected to an internal signal conditioning circuit which drives the internal feedback node. The user applies a trim voltage to the external pin and the signal conditioning circuit injects the required current into the feedback node to trim the output voltage.
How do you trim the output voltage of a power supply?
The most common methods of trimming the output voltage of power supplies are to inject a current (a voltage source with a high output impedance) into the feedback node or to change the value of an impedance element in the feedback network. The following are methods to implement output voltage trimming in power supplies.
How does a voltage source with a high output impedance work?
A voltage source with a high output impedance can be constructed by the user placing a high impedance resistor network between the output voltage of the power supply and ground. A node of this external resistor network is then connected to the internal feedback node pin and thus injects the proper current to trim the power supply output voltage.
How does a power supply 'pot' work?
The 'pot' is made available to the user to trim the power supply output voltage. The power supply design team provides a pin connected to an internal signal conditioning circuit which drives the internal feedback node.
Why can't the current or voltage be adjusted when using DC
When the power supply is in the "constant current" state, it can change the voltage and current on the load by adjusting the current and the voltage when it is in the "constant voltage" state.
