LTC6992CDCB-4#TRMPBF

Programmable Timers And Oscillators Overview

The LTC6992CDCB-4#TRMPBF is a silicon oscillator and voltage-controlled pulse width modulator (PWM) from Analog Devices. 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 provides a duty cycle range of 5% to 100%. 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 with <1.7% maximum frequency error
• Duty cycle limits of 5% minimum and 100% maximum
• 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 Mini Tape and Reel packaging. Confirm the DCB package designation corresponds to the 6-lead (2mm × 3mm) Plastic DFN form factor. Ensure the temperature grade 'C' aligns with the specified operating range of 0°C to 70°C for the application environment.

Programmable Timers And Oscillators Selection Notes

Select this part when a 5% to 100% duty cycle range is required. The LTC6992-1 offers 0%-100%, while the -2 and -3 variants are limited to 5%-95% or 0%-95%. Frequency accuracy depends on RSET tolerance; use precision resistors for optimal performance. The DIV pin sets the frequency divider ratio and output polarity.

Programmable Timers And Oscillators Part Context

This component belongs to the TimerBlox family of silicon timing devices. The LTC6992 series includes four versions differentiated by their duty cycle limits (-1: 0-100%, -2: 5-95%, -3: 0-95%, -4: 5-100%). The CDCB suffix denotes the commercial temperature grade and DFN package type.
