Key Features
- Voltage-controlled PWM oscillator spanning 0.00000318 MHz to 1 MHz (sub-Hz to 1 MHz) covering an extremely wide frequency range for timing, dimming, and modulation applications
- 5% to 100% pulse width control range via 0.1V to 0.9V control voltage, enabling smooth analog duty-cycle modulation without a microcontroller
- Compact SOT-23-6 surface-mount package enabling PWM generation in minimal board space for LED dimmers, motor speed controllers, and analog modulators
Applications
The LTC6992CS6-4#TRMPBF is designed for analog PWM generation applications where duty cycle must be controlled by a voltage signal rather than a digital processor, such as LED brightness dimming, fan speed control, and DC motor speed regulation. Its voltage-controlled oscillator frequency range from sub-Hz up to 1 MHz allows it to serve both very slow duty-cycle modulation tasks and higher-speed switching applications in a single device. The SOT-23-6 package makes it ideal for space-constrained designs in consumer electronics, industrial controls, and portable equipment where a simple analog-controlled PWM source is needed.

Frequently Asked Questions
What is the PWM frequency range of LTC6992CS6-4#TRMPBF and how is it set?
The LTC6992CS6-4#TRMPBF provides a PWM output frequency range from approximately 0.00000318 MHz (about 3.18 Hz) to 1 MHz. Frequency is set by an external resistor connected to the frequency-setting pin, allowing designers to select any frequency within this 5-decade range to match their switching regulator, LED dimmer, or motor control application requirements.
How does the 0.1V to 0.9V control voltage of LTC6992CS6-4#TRMPBF translate to duty cycle, and what does 5% to 100% range enable?
Applying 0.1V to the control input sets the duty cycle to approximately 5%, while 0.9V sets it to 100%. The 0.8V control span maps linearly to the 95% duty cycle swing, allowing a simple DAC or analog signal (such as a sensor output or potentiometer) to directly modulate the PWM duty cycle from nearly off to fully on without requiring a microcontroller or software.
For an analog LED dimmer circuit, what advantages does LTC6992CS6-4#TRMPBF offer over a microcontroller-based PWM solution?
The LTC6992CS6-4#TRMPBF requires no firmware development, no clock source, and no startup time—it generates PWM immediately when powered. It operates continuously at frequencies up to 1 MHz, above the 20 kHz audible range for silent dimming, while consuming significantly less PCB area in its SOT-23-6 package than any MCU-based solution. This reduces cost, BOM complexity, and design risk for simple single-channel dimming applications.
When should a designer choose LTC6992CS6-4#TRMPBF variant -4 over other LTC6992 variants for their application?
The LTC6992 family includes variants differing in frequency range and polarity. Variant -4 covers the 0.00000318 MHz to 1 MHz range with the specific 5% to 100% duty cycle behavior suited for applications needing a wide sub-Hz to 1 MHz span. Designers choose variant -4 when they need the broadest frequency range including very low frequencies (down to approximately 3 Hz) for slow modulation tasks like thermal control loops, while retaining the ability to reach 1 MHz for switching converter timing.
