Product details
Overview
LTC6992HS6-3#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 2.25V to 5.5V supply. Used in LED dimming, heater control, and servo loops where stable, low-drift PWM generation is required.
For engineers reviewing the LTC6992HS6-3#TRPBF datasheet, LTC6992HS6-3#TRPBF pinout, LTC6992HS6-3#TRPBF application, or LTC6992HS6-3#TRPBF equivalent, this page provides verified technical context, package-specific pin functions, real-world application mappings, and validated alternative options for automotive-grade timing control designs.
Technical Context
The LTC6992HS6-3#TRPBF implements a master oscillator with fixed 1 MHz reference scaled by ISET current (set via RSET), followed by an 8-step programmable divider (NDIV = 1, 4, 16…16384) controlled by a 4-bit A/D converter on the DIV pin. Its PWM transfer function maps MOD pin voltage (0.1×VSET to 0.9×VSET) linearly to output duty cycle, clamped at 0% min / 95% max per version -3 specification.
VSET is internally regulated to 1.00 V ±30 mV, making frequency setting insensitive to supply drift when using RSET. The device features CMOS output capable of sourcing/sinking 20 mA, 500 µs startup time, and guaranteed operation from –40°C to +125°C in the TSOT-23 package - meeting AEC-Q100 requirements for automotive environments.

Pinout & Package
Package: 6-lead Plastic TSOT-23 (S6), 1 mm profile, lead-free, RoHS-compliant. Exposed pad not present in S6 variant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V+ | Positive supply input | Accepts 2.25 V–5.5 V; must be bypassed with 0.1 µF capacitor directly to GND for stable oscillation. |
| DIV | Programmable divider & polarity input | 4-bit A/D input; resistor divider sets NDIV (1–16384) and output polarity (POL bit); <100 pF capacitance required. |
| SET | Frequency-setting node | Internally regulated to 1.00 V; connects to RSET (50 kΩ–800 kΩ) to set 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 version -3. |
| GND | Ground reference | Low-inductance connection point for all bypass caps and signal returns; ties internal regulator and A/D ground. |
| OUT | CMOS PWM output | Full-rail swing (GND to V+); 30 Ω typical output impedance; drives 20 mA load directly - no external buffer needed. |
Key Features
| Feature | Design Value |
|---|---|
| Voltage-controlled PWM | 0.1 V–0.9 V analog input directly maps to 0%–95% duty cycle with <3.7% error - eliminates DAC and software PWM overhead. |

FAQ
What is the exact duty cycle range supported by the LTC6992HS6-3#TRPBF?
The LTC6992HS6-3#TRPBF supports a 0% to 95% duty cycle range. This means the output can be fully off (0% on-time) or up to 95% on-time, with linear modulation between those limits via the MOD pin voltage (0.1×VSET to 0.9×VSET). At extremes outside this range, the output clamps - not inverted or stopped - distinguishing it from the -1 (0%–100%) and -2 (5%–95%) variants.
How is the output frequency programmed on the LTC6992HS6-3#TRPBF?
The LTC6992HS6-3#TRPBF uses two independent programming paths: RSET resistor (50 kΩ to 800 kΩ) between SET and GND sets the master oscillator frequency, while a resistor divider on the DIV pin selects one of eight divider ratios (NDIV = 1, 4, 16…16384). The final output frequency is fOUT = (1 MHz × 50 kΩ) / (NDIV × RSET), enabling precise, trim-free configuration from 3.81 Hz to 1 MHz.
Does the LTC6992HS6-3#TRPBF require external components to operate?
Yes - the LTC6992HS6-3#TRPBF requires at minimum a 0.1 µF bypass capacitor between V+ and GND, an RSET resistor (50 kΩ–800 kΩ) from SET to GND, and optionally a resistor divider on the DIV pin. No external crystal, PLL loop filter, or DAC is needed - all timing and PWM generation is self-contained within the LTC6992HS6-3#TRPBF.
Is the LTC6992HS6-3#TRPBF qualified for automotive applications?
Yes - the LTC6992HS6-3#TRPBF is AEC-Q100 qualified for automotive applications and specified for operation from –40°C to +125°C. Its internal VSET regulation, low frequency drift (±0.005%/°C), and robust pin architecture make it suitable for engine control modules, ADAS lighting, and battery management systems where reliability under thermal stress is critical.
What is the maximum output drive capability of the LTC6992HS6-3#TRPBF?
The LTC6992HS6-3#TRPBF features a CMOS output stage that sources and sinks up to ±20 mA while maintaining rail-to-rail swing (GND to V+). Output resistance is ~30 Ω, enabling direct drive of logic inputs, small MOSFET gates, or LED strings with appropriate series limiting resistors - no external buffer or driver IC is required for most low-to-medium power PWM applications.
