3 / 14 page KA7540 KA7540 KA7540 KA7540 3 3 3 3 Pin Assignments Pin Assignments Pin Assignments Pin Assignments Pin Definitions Pin Definitions Pin Definitions Pin Definitions Pin Number Pin Number Pin Number Pin Number Pin Name Pin Name Pin Name Pin Name Pin Function Description Pin Function Description Pin Function Description Pin Function Description 1CS Soft start capacitor connection pin. The pin voltage determines the phase of soft start, normal and dimming mode. 2CT Timing capacitor connection pin. The timing capacitor is charged and discharged to generate the sawtooth waveform that determines the oscillation frequency in the internal oscillator block. 3Vdim Input to the dimming stage. The pin voltage sets the switching frequency in dimming mode. 4 Ldet Input to the protection circuit. If the pin voltage is lower than 2V, the output of the gate driver is inhibited. 5 GND The ground potential of all the pins. 6OUT 2 The output of a high current power driver capable of driving the gate of a power MOSFET. 7OUT 1 The output of a high current power driver capable of driving the gate of a power MOSFET. 8VCC The logic and control power supply connection. 1 2 3 4 5 6 7 8 CS Ct Ldet VCC OUT1 OUT2 GND (Top View) Vdim |
