3961 General Description

Internal PWM Current Control. The A3961S * contains a fixed off-time pulse-width modulated (PWM) currentcontrol circuit that can be used to limit the load current to a desired value. The peak value of the current limiting (ITRIP) is set by the selection of an external current-sensing resistor.
