Abstract

We describe systems for forward power converters, in particular a bi - level current sense circuit to enable a single current sense input to provide two different current sense levels. The circuit comprises: a single current sense input connected to a current sense r esistor via a second resistor, for coupling in series with a power switch to generate a current sense signal for current through the switch; first and second comparators sharing a connection to the current sense input and having respective first and second outputs coupled to a controller, these being configured to compare a voltage on said shared input connection against different respective first and second threshold values; and a current generator coupled to said shared input connection. This enables third and fourth bi - level current sense threshold values to be set independently by said current sense and second resistors without changing said first and second threshold values.
