Product details
Overview
LTC6992IS6-4#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 5% to 100% programmable duty cycle range, operates from 2.25V to 5.5V supply, supports output frequencies from 3.81Hz to 1MHz via RSET and DIV pin configuration, and features CMOS output capable of ±20mA drive - used in LED dimming, heater control, and servo loop applications.
For engineers reviewing the LTC6992IS6-4#TRPBF datasheet, LTC6992IS6-4#TRPBF pinout, LTC6992IS6-4#TRPBF application, or LTC6992IS6-4#TRPBF equivalent, this device offers verified automotive-grade (-40°C to 85°C) operation, <3.7% PWM duty cycle error, 115μA typical supply current at 100kHz, and SOT-23-6 packaging for space-constrained embedded timing designs.
Technical Context
The LTC6992IS6-4#TRPBF implements a master oscillator with fixed 1MHz reference scaling, where frequency is set by RSET (50kΩ–800kΩ) and divided by NDIV (1–16384) selected via a resistor divider on the DIV pin. Its internal 4-bit A/D converter interprets VDIV to generate DIVCODE, determining both division ratio and polarity inversion (POL bit).
Duty cycle is linearly controlled by VMOD input (0.1•VSET to 0.9•VSET), with clamping at 5% min / 100% max per its -4 variant specification. The SET pin regulates VSET to 1.00V ±30mV, decoupling frequency accuracy from supply variation and enabling stable operation across temperature and voltage.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Frequency Range | 3.81Hz to 1MHz - enables ultra-low-power sleep-mode timing or high-speed PWM control without external clock sources. |
| Duty Cycle Range | 5% to 100% - supports full-range analog modulation including hard-off (5%) and continuous-on (100%) states for safety-critical or zero-crossing switching. |
| Frequency Accuracy | ±1.7% max over temperature - ensures predictable timing in closed-loop systems like thermal regulation without calibration. |
| PWM Duty Cycle Error | <3.7% max - guarantees consistent light intensity or power delivery across operating conditions in LED/Heater control. |
| Supply Voltage | 2.25V to 5.5V - compatible with Li-ion, 3.3V logic, and industrial 5V rails without level-shifting. |
| Supply Current | 115μA at 100kHz - extends battery life in portable equipment and reduces self-heating in sealed enclosures. |
| Operating Temperature | –40°C to +85°C - qualified for industrial and automotive cabin environments per I-grade specification. |
Pinout & Package
Package: 6-lead TSOT-23 (S6), 1mm profile, RoHS-compliant, lead-free finish. Exposed pad not present in S6 package.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V+ (Pin 1) | Power supply input | Accepts 2.25V–5.5V; requires local 0.1µF bypass to GND for noise immunity and stable oscillation. |
| DIV (Pin 2) | Programmable divider & polarity select | Resistor-divider input interpreted as 4-bit code (DIVCODE); sets NDIV (1–16384) and output polarity (POL bit). |
| SET (Pin 3) | Frequency-setting node | Internally regulated to 1.00V; ISET = VSET/RSET programs master oscillator - RSET = 50kΩ–800kΩ defines fOUT. |
| MOD (Pin 4) | Analog PWM control input | 0.1•VSET to 0.9•VSET (≈100mV–900mV) linearly controls duty cycle; clamps at 5%/100% for LTC6992-4 variant. |
| GND (Pin 5) | Ground reference | Low-inductance connection point for all bypass caps and signal returns; critical for jitter and stability performance. |
| OUT (Pin 6) | CMOS PWM output | Full-rail swing (GND to V+), 30Ω output impedance, ±20mA drive - directly interfaces LEDs, MOSFET gates, or optocouplers. |
Key Features
| Feature | Design Value |
|---|---|
| Voltage-controlled PWM | 0V–1V analog MOD input maps linearly to 5%–100% duty cycle - eliminates need for microcontroller DAC or digital PWM generation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage-controlled PWM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LTC6992IS6-2#TRPBF | 5%–95% duty cycle range; identical pinout, supply, and frequency specs. | Cannot achieve 100% duty cycle - unsuitable for applications requiring continuous conduction (e.g., latching solenoids). | Select only if 95% upper limit suffices and 100% clamp is unnecessary. |
| LTC6992HS6-4#TRPBF | Same functionality and duty cycle range, but rated for –40°C to +125°C (H-grade). | Validated for under-hood automotive use; higher thermal derating and extended qualification testing. | Choose when operating beyond +85°C ambient - e.g., engine control modules or power inverters. |
Compared with LTC6992IS6-4#TRPBF, the -2 variant trades 100% duty cycle capability for marginally tighter mid-range linearity, while the H-grade version retains identical electrical behavior but adds extended temperature validation - making the I-grade optimal for cost-sensitive industrial and cabin-level automotive designs.

FAQ
What is the minimum and maximum duty cycle supported by the LTC6992IS6-4#TRPBF?
The LTC6992IS6-4#TRPBF supports a guaranteed 5% minimum and 100% maximum duty cycle range. This is defined by its -4 variant designation and confirmed in the Electrical Characteristics table under DMIN and DMAX parameters. At VMOD = 0.1•VSET, output clamps at 5%; at VMOD = 0.9•VSET, it reaches 100%, enabling full-range analog control including hard-off and continuous-on states.
How is the output frequency programmed on the LTC6992IS6-4#TRPBF?
The LTC6992IS6-4#TRPBF output frequency is programmed using two elements: a resistor (RSET) between SET and GND sets the master oscillator frequency (fMASTER = 1MHz × 50kΩ / RSET), and a resistor divider on the DIV pin selects NDIV (1–16384) to produce fOUT = fMASTER / NDIV. RSET values from 50kΩ to 800kΩ yield the full 3.81Hz–1MHz range.
Does the LTC6992IS6-4#TRPBF require an external crystal or resonator?
No, the LTC6992IS6-4#TRPBF is a fully integrated silicon oscillator and requires no external crystal, resonator, or capacitor for basic operation. Its timing core is monolithic, relying solely on RSET and the DIV resistor divider for frequency and division control - simplifying BOM and improving reliability in harsh environments.
What is the operating temperature range for the LTC6992IS6-4#TRPBF?
The LTC6992IS6-4#TRPBF is specified for operation from –40°C to +85°C (I-grade). This is confirmed in the Order Information table and Absolute Maximum Ratings section. It is AEC-Q100 qualified for automotive applications and suitable for industrial environments where extended temperature stability is required.
Can the LTC6992IS6-4#TRPBF drive a MOSFET gate directly?
Yes, the LTC6992IS6-4#TRPBF CMOS output can directly drive most low-to-medium-side N-channel MOSFET gates. With ±20mA drive strength, 30Ω output impedance, and rail-to-rail swing (GND to V+), it provides sufficient peak current for fast turn-on/turn-off of MOSFETs with gate charges ≤30nC - verified in typical application circuits in the datasheet.
