LTC6992IS6-3#TRMPBF

Programmable Timers And Oscillators Overview

The LTC6992IS6-3#TRMPBF is a silicon oscillator and voltage-controlled pulse width modulator (PWM) from the TimerBlox family, manufactured by Analog Devices Inc. It operates on a single supply of 2.25V to 5.5V with a typical supply current of 115µA at 100kHz. The output frequency ranges from 3.81Hz to 1MHz, determined by an external resistor RSET and an internal divider NDIV. The duty cycle is controlled via a 0V to 1V analog input on the MOD pin. This specific variant supports a PWM duty cycle range of 0% to 95%. It features a CMOS output driver capable of sourcing or sinking 20mA and is housed in a 6-lead TSOT-23 package.

Programmable Timers And Oscillators Procurement Notes

Verify the component marking L TFCQ corresponds to the specified part number. Confirm the operating temperature range is –40°C to 85°C for the IS6 grade. Ensure the packaging suffix #TRMPBF indicates tape and reel mini quantity as per manufacturer specifications.

Programmable Timers And Oscillators Selection Notes

Select this variant when a 0% to 95% duty cycle limit is required. The IS6 designation specifies the industrial temperature range and TSOT-23 package. Verify that the DIV pin configuration provides the necessary frequency division ratio and polarity settings for the target application.

Programmable Timers And Oscillators Part Context

This component belongs to the LTC6992 series, which includes four variants differing only in their minimum and maximum duty cycle limits. The -3 suffix denotes the 0% to 95% duty cycle capability. Other series members include the -1 (0%-100%), -2 (5%-95%), and -4 (5%-100%) options.

Programmable Timers And Oscillators Replacement Considerations

Direct functional substitutes within the same family include LTC6992IS6-1#TRMPBF, LTC6992IS6-2#TRMPBF, and LTC6992IS6-4#TRMPBF. These share identical electrical characteristics except for the duty cycle clamp limits. Cross-package replacements require verifying pin compatibility between TSOT-23 and DFN formats.
