pin FuncTions
V+ (Pin 1/Pin 5): Supply Voltage (2.25V to 5.5V). This sup-
ply should be kept free from noise and ripple. It should be
bypassed directly to the GND pin with a 0.1μF capacitor.
DIV (Pin 2/Pin 4): Programmable Divider and Polarity
Input. The DIV pin voltage (VDIV) is internally converted
into a 4-bit result (DIVCODE). VDIV may be generated by
a resistor divider between V+ and GND. Use 1% resistors
to ensure an accurate result. The DIV pin and resistors
should be shielded from the OUT pin or any other traces
that have fast edges. Limit the capacitance on the DIV pin
to less than 100pF so that VDIV settles quickly. The MSB of
DIVCODE (POL) determines if the PWM signal is inverted
before driving the output. When POL = 1 the transfer func-
tion is inverted (duty cycle decreasing as VMODincreases).
SET (Pin 3/Pin 3): Frequency-Setting Input. The voltage
on the SET pin (VSET) is regulated to 1V above GND. The
amount of current sourced from the SET pin (ISET) pro-
grams the master oscillator frequency. The ISET current
range is 1.25μA to 20μA. The output oscillation will stop
if ISET drops below approximately 500nA. A resistor con-
nected between SET and GND is the most accurate way to
set the frequency. For best performance, use a precision
metal or thin film resistor of 0.5% or better tolerance and
50ppm/°C or better temperature coefficient. For lower ac-
curacy applications an inexpensive 1% thick film resistor
may be used.
Limit the capacitance on the SET pin to less than 10pF
to minimize jitter and ensure stability. Capacitance less
than 100pF maintains the stability of the feedback circuit
regulating the VSET voltage.

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 0.9VSET
(approximately 100mV to 900mV). Beyond those limits,
the output will either clamp at 5% or 95%, or stop oscil-
lating (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
fromGNDtoV+withanoutputresistanceofapproximately
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.
