PIN FUNCTIONS (DCB/S6)
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 VSET and 0.9 VSET
(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+ with an output resistance of approximately
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
source/sink current to 20mA.
