Product details
Overview
LTC6992IS6-3#TRPBF from Analog Devices is a voltage-controlled pulse width modulator (PWM) IC in the TimerBlox family, designed for precision analog duty-cycle control. It delivers 0% to 95% duty cycle range, programmable output frequency from 3.81 Hz to 1 MHz via RSET and DIV pin, and operates from 2.25 V to 5.5 V supply. Used in LED dimming and heater control where stable, low-drift PWM generation is required.
For engineers reviewing the LTC6992IS6-3#TRPBF datasheet, LTC6992IS6-3#TRPBF pinout, LTC6992IS6-3#TRPBF application, or LTC6992IS6-3#TRPBF equivalent, this page provides verified specifications, SOT-23-6 package details, temperature-rated performance (–40°C to +85°C), and real-world design guidance for analog-controlled timing systems.
Technical Context
The LTC6992IS6-3#TRPBF integrates a master oscillator with 1 MHz base frequency, a 4-bit A/D converter for DIV pin voltage decoding, and a digital filter to stabilize PWM output. Its SET pin regulates VSET to 1.00 V ±30 mV, enabling precise frequency setting via external RSET (50 kΩ to 800 kΩ).
Duty cycle is linearly controlled by MOD pin voltage (0.1·VSET to 0.9·VSET), with clamping at 0% min / 95% max per its -3 variant designation. Output features CMOS drive capability (±20 mA), 500 µs startup time, and <3.7% PWM duty cycle error across temperature and supply variations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Frequency Range | 3.81 Hz to 1 MHz - set by RSET (50 kΩ–800 kΩ) and NDIV (1–16384), enabling ultra-low-power timing or high-speed PWM. |
| Duty Cycle Range | 0% to 95% - supports full-off operation and near-full-on drive without oscillation stop, ideal for LED dimming with deep turn-off. |
| Frequency Accuracy | ±1.7% max over –40°C to +85°C - ensures stable timing in industrial environments without calibration. |
| Supply Voltage | 2.25 V to 5.5 V - compatible with Li-ion, 3.3 V, and 5 V systems; includes 1.95 V power-on reset threshold. |
| Supply Current | 105 µA to 450 µA - scales with NDIV and RSET; as low as 105 µA at V+ = 2.25 V, RSET = 800 kΩ, NDIV ≥ 16. |
| Output Drive | ±20 mA CMOS - directly drives LEDs, logic inputs, or small MOSFET gates without external buffers. |
| Operating Temperature | –40°C to +85°C - qualified for industrial and automotive-grade applications (I-grade). |
Pinout & Package
Package: 6-lead Plastic TSOT-23 (S6), 1 mm profile, RoHS-compliant, lead-free finish. Exposed pad not present in SOT-23 variant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V+ | Positive supply input | 2.25 V to 5.5 V supply; requires local 0.1 µF bypass to GND for noise immunity. |
| DIV | Programmable divider & polarity select | 4-bit A/D input; resistor divider sets NDIV (1–16384) and output polarity (POL bit). |
| SET | Frequency-setting reference | Internally regulated to 1.00 V; ISET = VSET/RSET programs master oscillator frequency. |
| MOD | Analog PWM control input | 0.1·VSET to 0.9·VSET (≈100 mV–900 mV) linearly controls duty cycle; clamps at 0%/95% for LTC6992-3. |
| GND | Ground reference | Low-inductance return path; ties to PCB ground plane for jitter and EMI control. |
| OUT | PWM output driver | CMOS rail-to-rail output; sources/sinks up to ±20 mA; rise/fall times <2.7 ns (V+ = 2.25 V). |
Key Features
| Feature | Design Value |
|---|---|
| Voltage-controlled PWM | 0.1 V to 0.9 V analog input (referenced to VSET) enables simple DAC-less dimming and control loops. |
| Eight selectable frequency dividers | NDIV = 1, 4, 16, 64, 256, 1024, 4096, 16384 - allows one RSET value to cover 16+ decades of output frequency. |
| 0% to 95% duty cycle limit | Enables true off-state (0%) and high-brightness LED drive (95%) without external blanking circuitry. |
| Low quiescent current | As low as 105 µA at 2.25 V - extends battery life in portable equipment and sensor nodes. |
| Industrial temperature grade | –40°C to +85°C guaranteed operation - suitable for factory automation, motor control, and outdoor electronics. |

FAQ
What is the duty cycle range of the LTC6992IS6-3#TRPBF?
The LTC6992IS6-3#TRPBF has a confirmed duty cycle range of 0% to 95%, as specified in the device family datasheet for the -3 variant. This allows full output disable (0%) and near-maximum conduction (95%) without oscillation stop or clipping beyond those limits. The range is enforced internally and does not require external components.
How is the output frequency programmed on the LTC6992IS6-3#TRPBF?
The LTC6992IS6-3#TRPBF output frequency is set using two elements: an external resistor (RSET) connected between SET and GND determines the master oscillator frequency, while the DIV pin voltage selects the division ratio (NDIV = 1, 4, 16…16384). The final fOUT = 1 MHz × 50 kΩ / (NDIV × RSET), with RSET ranging from 50 kΩ to 800 kΩ.
What supply voltage range does the LTC6992IS6-3#TRPBF support?
The LTC6992IS6-3#TRPBF operates from 2.25 V to 5.5 V, with a power-on reset threshold of 1.95 V. It maintains full specification compliance-including ±1.7% frequency accuracy and 0%–95% duty cycle-across this entire range and over its –40°C to +85°C operating temperature.
Does the LTC6992IS6-3#TRPBF require external capacitors for stability?
The LTC6992IS6-3#TRPBF requires only a 0.1 µF ceramic capacitor between V+ and GND, placed close to the pins. No capacitor is needed on SET or MOD pins unless layout demands filtering; capacitance >10 pF on SET degrades jitter, and >100 pF on DIV slows settling. The internal VSET regulator and digital filter eliminate need for external timing caps.
Is the LTC6992IS6-3#TRPBF pin-compatible with other TimerBlox devices?
The LTC6992IS6-3#TRPBF uses the standard 6-lead TSOT-23 (S6) footprint shared across all LTC6992 variants (e.g., -1, -2, -4), with identical pinout (V+, DIV, SET, MOD, GND, OUT). Functionally, only the duty cycle limits differ; RSET, DIV divider, and MOD interface remain fully interchangeable across the family.
