LTC6992IS6-4#TRMPBF

LTC6992-4 is a TimerBlox voltage-controlled pulse width modulator (PWM). It is a silicon oscillator with an easy-to-use analogue voltage-controlled pulse width modulation (PWM) capability. This part of the TimerBlox® family of versatile silicon timing devices. A single resistor, RSET, programs the LTC6992’s internal host oscillator frequency. The output frequency is determined by this host 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. Application includes PWM servo loops, heater control, LED dimming control, high vibration, high acceleration environments, portable and battery-powered equipment.
