LTC6992IDCB-3#TRMPBF

Programmable Timers And Oscillators Overview

The LTC6992IDCB-3#TRMPBF is a silicon oscillator from the TimerBlox family, functioning as a voltage-controlled pulse width modulator (PWM). It generates PWM signals with a frequency range of 3.81 Hz to 1 MHz, determined by an external resistor on the SET pin and an internal programmable divider. The duty cycle is controlled via a 0V to 1V analog input on the MOD pin. This specific variant supports a duty cycle range of 0% to 95%. It operates on a single supply voltage between 2.25 V and 5.5 V, drawing approximately 115 µA at 100 kHz. The device features a CMOS output driver capable of sourcing or sinking 20 mA 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 3.81 Hz to 1 MHz set by a single resistor
• Duty cycle limits of 0% minimum and 95% maximum
• CMOS output driver with 20 mA source/sink capability

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 containing 500 units. Confirm the IDCB designation corresponds to the industrial temperature grade (-40°C to 85°C) and the DCB package type. Ensure compatibility with the specific duty cycle constraints of the -3 variant before procurement.

Programmable Timers And Oscillators Selection Notes

Select the LTC6992IDCB-3#TRMPBF when a 0% to 95% duty cycle range is required. The 'I' suffix specifies operation within the -40°C to 85°C temperature range. The 'DCB' indicates the 2mm x 3mm DFN package. Verify that the application does not require the full 100% duty cycle available in the -1 or -4 variants.

Programmable Timers And Oscillators Part Context

This component belongs to the LTC6992-1/2/3/4 series of TimerBlox silicon oscillators. The -3 suffix specifically defines the duty cycle clamp behavior, allowing 0% minimum but limiting the maximum to 95%. It shares the same core architecture and pinout as the -1, -2, and -4 variants, differing only in these duty cycle limits.

Programmable Timers And Oscillators Replacement Considerations

Direct functional replacements include other members of the LTC6992 series such as LTC6992IDCB-1#TRMPBF or LTC6992IDCB-4#TRMPBF, provided the duty cycle limits are acceptable. Cross-package alternatives like the SOT-23 version (IS6) are available if pin compatibility allows.
