Description
Internal Darlington switch collector.
Internal Darlington switch emitter.
Timing Capacitor to control the switching frequency.
Ground pin for all internal circuits.
Inverting input pin of internal comparator.
Voltage Supply
Peak Current Sense Input to monitor the voltage drop across an external
resistor to limit the peak current through the circuit.
ON/OFF Pin. To disable the device, this input should be pulled below
0.8 V. If the pin is left floating, it will be disabled.
