LTC6992IDCB-1#TRMPBF

Programmable Timers And Oscillators Overview

The LTC6992IDCB-1#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, programmed via a single resistor RSET and an internal divider NDIV. Duty cycle control is achieved through a 0V to 1V analog input on the MOD pin. This specific variant supports a duty cycle range of 0% to 100%. It features a CMOS output driver capable of sourcing or sinking 20mA, with rise and fall times under 3ns.

Programmable Timers And Oscillators Feature Summary

• Voltage-controlled PWM with 0V to 1V analog input for duty cycle adjustment

• Programmable frequency divider with ratios 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 component marking LDXC and package type DCB (6-Lead DFN) against the datasheet. Confirm the operating temperature range is –40°C to 85°C. Ensure the suffix #TRMPBF indicates tape and reel mini packaging. Check for AEC-Q100 qualification if automotive reliability is required, though this specific part number is not designated with the #W suffix for controlled automotive manufacturing.

Programmable Timers And Oscillators Selection Notes

Select the LTC6992IDCB-1#TRMPBF when a full 0% to 100% duty cycle range is required. The 'I' grade ensures performance from –40°C to 85°C. The 'DCB' package is a 2mm x 3mm plastic DFN. Use the DIV pin to set the frequency divider ratio between 1 and 16384. Ensure the MOD pin voltage stays within 0.1*VSET to 0.9*VSET for linear operation.

Programmable Timers And Oscillators Part Context

This part belongs to the LTC6992 series, which includes variants with different duty cycle limits (-1: 0-100%, -2: 5-95%, -3: 0-95%, -4: 5-100%). The IDCB-1 variant specifically allows oscillations to stop at extreme duty cycles due to its 0% minimum and 100% maximum limits. It shares the same electrical characteristics as other LTC6992-1 parts but differs in package and temperature grade.

Programmable Timers And Oscillators Replacement Considerations

LTC6992CDCB-1#TRMPBF offers the same function with a commercial temperature range (0°C to 70°C). LTC6992MPS6-1#TRMPBF provides an industrial temperature range (-55°C to 125°C) in a SOT-23-6 package. Substitutes must match the -1 suffix for 0-100% duty cycle capability.
