Product Details

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.

Applications

  • PWM Servo Loops
  • Heater Control
  • LED Dimming Control
  • High Vibration, High Acceleration Environments
  • Portable and Battery-Powered Equipment
