#### Typical Application

#### Description

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 devices.

A single resistor, R_{SET}, programs the LTC6992’s internal master oscillator frequency. The output frequency is determined by this master oscillator and an internal frequency divider, N_{DIV}, programmable to eight settings from 1 to 16384.
