PIN FUNCTIONS
MOD (Pin 4/Pin 1): Pulse-Width Modulation Input. The
voltage on the MOD pin controls the output duty cycle. The
linear control range is between 0.1 • V
(approximately 100mV to 900mV). Beyond those limits, the
output will either clamp at 5% or 95%, or stop oscillating
(0% or 100% duty cycle), depending on the version.

GND (Pin 5/Pin 2): Ground. Tie to a low inductance ground
plane for best performance.
OUT (Pin 6/Pin 6): Oscillator Output. The OUT pin swings
from GND to V
30Ω. The duty cycle is determined by the voltage on the
MOD pin. When driving an LED or other low-impedance
load a series output resistor should be used to limit the
source/sink current to 20mA.
