LTC6992IS6-3#TRPBF

Programmable Timers And Oscillators Overview

The LTC6992IS6-3#TRPBF is a silicon oscillator featuring voltage-controlled pulse width modulation (PWM) capability, part of the TimerBlox family. It operates on a single 2.25V to 5.5V supply 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, offering a range of 0% to 95%. The device provides a CMOS output capable of sourcing or sinking 20mA.

Programmable Timers And Oscillators Feature Summary

• Voltage-controlled PWM with 0% to 95% duty cycle range
• Frequency range of 3.81Hz to 1MHz using a single RSET resistor
• Internal programmable divider NDIV selectable from 1 to 16384
• CMOS output driver with 20mA 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 specific suffix #TRPBF indicates tape and reel packaging when ordering. Confirm the IS6 designation corresponds to the industrial temperature range of –40°C to 85°C and the SOT-23 package type. Ensure compatibility with the required duty cycle limits for the -3 variant before finalizing procurement specifications.

Programmable Timers And Oscillators Selection Notes

Select the LTC6992IS6-3#TRPBF when a 0% to 95% duty cycle range is required. The 'I' grade ensures performance across the –40°C to 85°C temperature range. The 'S6' indicates the TSOT-23 package. Verify that the application does not require 100% duty cycle, as this variant clamps at 95% maximum.

Programmable Timers And Oscillators Part Context

This component belongs to the LTC6992 series, which includes four variants (-1, -2, -3, -4) differing primarily in their minimum and maximum duty cycle limits. The -3 version specifically allows for 0% minimum duty cycle but caps the maximum at 95%, distinguishing it from the -1 and -4 versions which support 100% maximum duty cycle.

Programmable Timers And Oscillators Replacement Considerations

Direct replacements within the same family include LTC6992IS6-1#TRPBF, LTC6992IS6-2#TRPBF, and LTC6992IS6-4#TRPBF. Note that these alternatives have different duty cycle clamp settings: -1 supports 0-100%, -2 supports 5-95%, and -4 supports 5-100%. Ensure the new part's duty cycle limits match the circuit requirements.
