LTC6992IDCB-2#TRMPBF

Programmable Timers And Oscillators Overview

The LTC6992IDCB-2#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 programmable divider NDIV (1 to 16384). Duty cycle is controlled via a 0V to 1V analog input on the MOD pin. This specific variant, the LTC6992-2, enforces a duty cycle range of 5% to 95%. It features a CMOS output capable of sourcing or sinking 20mA and is housed in a 6-lead DFN package.

Programmable Timers And Oscillators Feature Summary

• Voltage-controlled PWM with 0V to 1V analog input for duty cycle adjustment
• Frequency range of 3.81Hz to 1MHz using a single external resistor
• LTC6992-2 variant limits duty cycle between 5% and 95%
• CMOS output driver sources/sinks 20mA

Programmable Timers And Oscillators Applications

• PWM servo loops
• Heater control systems
• LED dimming control
• Portable and battery-powered equipment

Programmable Timers And Oscillators Procurement Notes

Verify the ordering suffix #TRMPBF indicates tape and reel mini packaging. Confirm the IDCB suffix corresponds to the industrial temperature grade (-40°C to 85°C) and the DCB package type (6-Lead Plastic DFN). Ensure the -2 suffix is selected to enforce the 5% to 95% duty cycle limits required for the application.

Programmable Timers And Oscillators Selection Notes

Select the LTC6992IDCB-2#TRMPBF when an industrial temperature range (-40°C to 85°C) is required alongside a 5% to 95% duty cycle constraint. Use this part instead of the -1, -3, or -4 variants if oscillation stopping at 0% or 100% duty cycle must be prevented. Verify that the 6-lead DFN package fits the PCB footprint constraints.

Programmable Timers And Oscillators Part Context

This component belongs to the LTC6992-1/2/3/4 family of TimerBlox silicon oscillators. The 'I' designation specifies the industrial temperature range, while 'DCB' identifies the 2mm x 3mm plastic DFN package. The '-2' suffix distinguishes it from other duty cycle limit configurations within the same package and temperature grade.

Programmable Timers And Oscillators Replacement Considerations

Direct functional substitutes within the same package and temperature grade include LTC6992IDCB-1#TRMPBF, LTC6992IDCB-3#TRMPBF, and LTC6992IDCB-4#TRMPBF. Note that these alternatives have different minimum and maximum duty cycle limits compared to the -2 variant.
