ADI LTC6992IS6-2#TRPBF

A silicon oscillator with an easy-to-use analog voltage-controlled pulse width modulation (PWM) capability. A single resistor, RSET, programs the internal 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. 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. For easy configuration, use the TimerBlox LTC6992: PWM Web-Based Design Tool.
