DFor more information FeedbackTYPICAL APPLICATIONDESCRIPTIONT imerBlox: Voltage-Controlled Pulse Width Modulator (PWM)The LTC 6992 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 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.

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 NAMEPWM DUTY CYCLE RANGELTC6992-10% to 100%LTC6992-25% to 95%LTC6992-30% to 95%LTC6992-45% to 100%For easy configuration of the LTC6992, use the TimerBlox LTC6992: PWM Web-Based Design Tool.
