Abstract
Disclosed herein is a circuit for regulating current flow and power dissipation. The circuit includes a power transistor generating a load current, a sense transistor producing a scaled version of the load current, and a regulation circuit equalizing drain-to-source voltages of both transistors. A current comparison circuit generates a feedback current based on the difference between a reference current and the scaled load current. A feedback circuit adjusts the power transistor's control voltage based on this feedback current. When the scaled load current is below the reference current, the feedback circuit decreases the power transistor's on-resistance, reducing power dissipation. Conversely, when the scaled load current exceeds the reference current, the feedback circuit increases the power transistor's on-resistance, limiting current flow. This dynamic adjustment mechanism optimizes power efficiency and current regulation, making the circuit suitable for applications requiring precise current control and minimal power loss.
