Current monitor for switching regulators |
摘要 |
A circuit arragement for monitoring current in a switching converter, wherein an inductance is charged pulse-wise with a current via a power switch. In accordance with the invention, the mean value of the voltage drop across the inductance is formed via an RC-component and the power switch is blocked via a threshold value switch when a predetermined maximum voltage drop is exceeded across the inductance.
