TimerBlox:
Voltage-Controlled Pulse
Width Modulator (PWM)
The LTC6992 is a silicon oscillator with an easy-to-use
analog voltage-controlled pulse width modulation (PWM)
capability. The LTC6992 is part of the TimerBlox family
of versatile silicon timing devices.
A single resistor, RSET, programs the LTC6992’s inter-
nal master oscillator frequency. The output frequency
is determined by this master oscillator and an internal
frequency divider, NDIV, programmable to eight settings
from 1 to 16384.

, NDIV = 1,4,16 …16384
Applying a voltage between 0V and 1V on the MOD pin
sets the duty cycle.
The four versions differ in their minimum/maximum duty
cycle. Note that a minimum duty cycle limit of 0% or
maximum duty cycle limit of 100% allows oscillations to
stop at the extreme duty cycle settings.
