What is a Current Mode Controller?

Current mode control is a power control method that is used with switching converter topologies. In a current mode controller, a dual loop control circuit adjusts the pulse-width modulation operation following a measured output voltage and output current. There are several advantages to using a current mode controlled switching power supply instead of a voltage mode switching power supply such as higher reliability, easy and accurate current sharing in high current multiphase designs and simple and reliable feedback loop compensation.

Types of Current Mode Controllers

There are many different kinds of current mode controllers. At Future Electronics we stock many of the most common types categorized by Maximum Supply Current, Maximum Frequency, Turn On Threshold Voltage, Turn Off Threshold Voltage, Maximum Duty Cycle, Packaging Type and Operating Temperature Range. The parametric filters on our website can help refine your search results depending on the required specifications.

The most common values for Maximum Frequency are 275 kHz. We also carry current mode controllers with Maximum Frequency as high as 2.2 MHz. Turn Off Threshold Voltage can be between 830 mV and 10 kV, with 10 V being the most common value.
