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 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.ApplicationsPWM Servo LoopsHeater ControlLED Dimming ControlHigh Vibration, High Acceleration EnvironmentsPortable and Battery-Powered Equipment
