OUTPUT
High peak current associated with capacity loads necessitate careful grounding techniques. Timing and bypass
capacitors should be connected close to pin 5 in single point GND. The transistor and 5k
potentio-meter are used
to sample the oscillator waveform and apply an adjustable Ramp to Pin 3.

During Under-Voltage Lockout, the output driver is biased to a high impedance state. Pin 6 should be shunt to
GND with a bleeder resistor to prevent activating the power switch with output leakage currents.
