LTC6992-1/LTC6992-2/ LTC6992-3/LTC6992-4 TimerBlox: Voltage-Controlled Pulse Width Modulator (PWM) Fea T Descrip T n Pulse Width Modulation (PWM) Controlled by The LTC 6992 is a silicon oscillator with an easy-to-use Simple 0V to 1V Analog Input analog voltage-controlled pulse width modulation (PWM) n Four Available Options Define Duty Cycle Limits capability. The LTC6992 is part of the TimerBlox family Minimum Duty Cycle at 0% or 5% of versatile silicon timing devices. Maximum Duty Cycle at 95% or 100% A single resistor, R , programs the LTC6992s inter- SET n Frequency Range: 3.81Hz to 1MHz nal master oscillator frequency. The output frequency n Configured with 1 to 3 Resistors is determined by this master oscillator and an internal n <1.7% Maximum Frequency Error frequency divider, N , programmable to eight settings DIV n PWM Duty Cycle Error < 3.7% Maximum from 1 to 16384. n Frequency Modulation (VCO) Capability 1MHz 50k n 2.25V to 5.5V Single Supply Operation f = ,N = 1,4,16 16384 OUT DIV n 115A Supply Current at 100kHz N R DIV SET n 500s Start-Up Time Applying a voltage between 0V and 1V on the MOD pin n CMOS Output Driver Sources/Sinks 20mA sets the duty cycle. n 55C to 125C Operating Temperature Range n The four versions differ in their minimum/maximum duty Available in Low Profile (1mm) SOT-23 (ThinSOT) cycle. Note that a minimum duty cycle limit of 0% or and 2mm 3mm DFN maximum duty cycle limit of 100% allows oscillations to stop at the extreme duty cycle settings. a T DEVICE NAME PWM DUTY CYCLE RANGE n PWM Servo Loops LTC6992-1 0% to 100% n Heater Control LTC6992-2 5% to 95% n LED Dimming Control LTC6992-3 0% to 95% n High Vibration, High Acceleration Environments LTC6992-4 5% to 100% n Portable and Battery-Powered Equipment For easy configuration of the LTC6992, download the L, LT, LTC and LTM, Linear Technology, TimerBlox and the Linear logo are registered trademarks and ThinSOT is a trademark of Linear Technology Corporation.
