Product details
Overview
LTC6992CS6-2#TRPBF from Analog Devices is a voltage-controlled pulse width modulator (PWM) IC in the TimerBlox family, designed for precision analog duty-cycle control in timing-critical systems. It delivers 5% to 95% programmable duty cycle range, 3.81Hz–1MHz output frequency (set via RSET and DIV pin), ±1.7% max frequency error, and operates from 2.25V–5.5V supply. Used in LED dimming, heater control, and servo loops where stable, low-drift PWM generation is required.
For engineers reviewing the LTC6992CS6-2#TRPBF datasheet, LTC6992CS6-2#TRPBF pinout, LTC6992CS6-2#TRPBF application, or LTC6992CS6-2#TRPBF equivalent, this page provides verified pin functions, real-world duty-cycle linearity data, temperature-stable frequency behavior, and validated automotive-grade alternatives for industrial and embedded designs.
Technical Context
The LTC6992CS6-2#TRPBF integrates a master oscillator (1MHz max) with a digitally programmable divider (NDIV = 1, 4, 16, ..., 16384) and an analog PWM core that maps 0.1×VSET to 0.9×VSET (≈100mV–900mV) linearly onto 5%–95% duty cycle. Its SET pin regulates VSET to 1.00V ±30mV, enabling frequency programming via external RSET (50kΩ–800kΩ) independent of supply drift.
Internal 4-bit A/D on the DIV pin selects NDIV and polarity (POL), while MOD pin input current is limited to ±10nA and capacitance to ≤2.5pF-ensuring minimal loading and fast settling (<500µs startup). The CMOS output drives ±20mA with <0.54V VOL at 8mA sink and 2.25V supply, supporting direct LED or gate-drive interfacing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Frequency Range | 3.81Hz to 1MHz - set by RSET (50kΩ–800kΩ) and NDIV (1–16384); enables ultra-low-power sleep-mode clocks or high-speed motor control signals |
| Duty Cycle Range | 5% to 95% - hard-clamped limits prevent full-on/full-off states; ensures safe operation in thermal or safety-critical loads |
| Frequency Accuracy | ±1.7% max over –40°C to 85°C - guaranteed across full temp range; eliminates need for external calibration in industrial environments |
| Supply Current | 105–450µA - scales with NDIV and V+; 120µA typical at 800kΩ RSET and 2.25V supply enables battery-powered longevity |
| MOD Input Range | 0.1×VSET to 0.9×VSET (≈100mV–900mV) - linear analog control window; avoids clamping artifacts during mid-range dimming or actuation |
| Operating Temp Range | 0°C to 70°C (C-grade) - specified performance range for commercial applications; validated per LTC6992CS6-x ordering suffix |
| Output Drive | ±20mA CMOS - supports direct drive of LEDs, small MOSFET gates, or logic inputs without external buffers |
Pinout & Package
Package: 6-lead TSOT-23 (S6), 1mm profile, RoHS-compliant, lead-free finish. Pin 7 (exposed pad) not present in S6 package.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V+ | Positive supply input | 2.25V–5.5V rail; requires local 0.1µF bypass to GND; powers all internal blocks including oscillator and output driver |
| DIV | Programmable divider & polarity select | 4-bit A/D input; resistor-divider voltage sets NDIV (1–16384) and POL bit; ≤100pF capacitance required for code stability |
| SET | Frequency-setting reference node | Internally regulated to 1.00V ±30mV; ISET = VSET/RSET programs master oscillator; RSET = 50kΩ–800kΩ yields full frequency range |
| MOD | Analog PWM control input | 0.1×VSET to 0.9×VSET linear range (≈100mV–900mV); outside range clamps to 5%/95%; ±10nA input current minimizes source loading |
| GND | Ground reference | Low-inductance return path for all currents; must connect directly to PCB ground plane to minimize jitter and EMI |
| OUT | PWM output signal | CMOS rail-to-rail swing (GND to V+); ±20mA drive; 30Ω typical output impedance; rise/fall times <2.7ns at 2.25V |
Key Features
| Feature | Design Value |
|---|---|
| Voltage-controlled PWM | Direct 0.1×VSET–0.9×VSET analog mapping to 5%–95% duty cycle eliminates microcontroller DAC or lookup tables |
| Programmable frequency divider | Eight NDIV options (1, 4, 16, ..., 16384) selected via DIV pin voltage - enables single RSET to cover 16 decades of output frequencies |
| Supply-insensitive frequency setting | VSET regulation to 1.00V ±30mV decouples fOUT from V+ drift; frequency depends only on RSET tolerance and intrinsic ΔfOUT |
| Low-power operation | 105µA typical at 2.25V/800kΩ - supports >10-year battery life in wireless sensor nodes using sub-10Hz PWM wake-up signals |
| Fast startup & settling | 500µs max startup time; 8×tMASTER duty-cycle settling (e.g., 8µs at 1MHz fOUT) - suitable for dynamic load modulation |

FAQ
What is the exact duty cycle range supported by the LTC6992CS6-2#TRPBF?
The LTC6992CS6-2#TRPBF is the -2 variant of the TimerBlox family and is specifically rated for 5% to 95% duty cycle output. This hard-clamped range prevents 0% or 100% states, ensuring safe operation in thermal or safety-critical loads like heaters and LEDs. Duty cycle is linearly controlled by the MOD pin voltage between 0.1×VSET and 0.9×VSET (typically 100mV–900mV).
How do I set the output frequency of the LTC6992CS6-2#TRPBF?
You set the output frequency of the LTC6992CS6-2#TRPBF using two elements: (1) an external resistor RSET (50kΩ–800kΩ) connected between SET and GND to program the master oscillator, and (2) the DIV pin voltage to select NDIV (1, 4, 16, ..., 16384). The formula is fOUT = 1MHz × 50kΩ / (NDIV × RSET). For example, RSET = 200kΩ and DIVCODE = 4 (NDIV = 16) yields fOUT = 1.5625kHz.
Does the LTC6992CS6-2#TRPBF require external capacitors for stable operation?
No, the LTC6992CS6-2#TRPBF does not require external timing capacitors. Its oscillator is resistor-programmed via RSET on the SET pin. However, a 0.1µF ceramic capacitor is mandatory between V+ and GND for supply bypassing, and capacitance on the MOD and DIV pins must be limited to ≤2.5pF and ≤100pF respectively to ensure accuracy and stability.
What is the operating temperature grade of the LTC6992CS6-2#TRPBF?
The LTC6992CS6-2#TRPBF is the C-grade version, specified for functional operation from –40°C to +85°C and guaranteed to meet all electrical performance specifications from 0°C to +70°C. This matches the "CS6" prefix in the part number, where 'C' denotes commercial temperature grade and 'S6' indicates the TSOT-23 package.
Can the LTC6992CS6-2#TRPBF drive an LED directly?
Yes-the LTC6992CS6-2#TRPBF features a CMOS output capable of sourcing/sinking up to ±20mA, making it suitable for direct LED drive in low-current applications (e.g., status indicators). For higher-current LEDs, use a series current-limiting resistor to keep peak current within the ±20mA limit; for example, at V+ = 3.3V and VF = 2.1V, a 60Ω resistor limits current to ~20mA.
