Product details
Overview
TPS92200D1RXLR from Texas Instruments is a 1.5-A synchronous buck LED driver with 4-V to 30-V input range, integrated 150-mΩ high-side and 90-mΩ low-side MOSFETs, 1-MHz switching frequency, 99-mV ±3-mV FB reference voltage, and dual PWM/analog dimming support-designed for IR LED drivers in video surveillance systems.
For engineers reviewing the TPS92200D1RXLR datasheet, TPS92200D1RXLR pinout, TPS92200D1RXLR application, or TPS92200D1RXLR equivalent, key selection criteria include verified 1.5-A continuous output capability, VQFN-HR (6) package thermal performance (RθJA = 136.1°C/W), ultra-low 1-μA shutdown current, peak-current-mode control with internal compensation, and confirmed LED open/short/thermal protection behavior per TI SLVSER4B Rev B.
Technical Context
The TPS92200D1RXLR implements peak-current-mode control with fixed 1-MHz switching frequency and internal slope compensation to prevent sub-harmonic oscillation across 4–30-V input and –40°C to +125°C operating junction temperature. Its error amplifier regulates LED current via 99-mV FB reference, with VCOMP compared against real-time high-side current sensing through RSENSE.
Dimming is implemented via two independent paths: digital PWM input (100 Hz–2 kHz) directly controls switch on/off timing, while analog input (0.65 V–1.2 V) scales the internal reference voltage linearly from 5% to 100% output current. Protection logic uses auto-retry hiccup mode triggered by FB overvoltage (>140 mV), thermal shutdown (>165°C), or NMOS current limit violation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 4 V to 30 V - supports 12-V industrial rails and 24-V PoE-powered lighting systems without external pre-regulation. |
| Output Current | 1.5 A continuous - delivers full brightness to multi-LED IR arrays (e.g., 4× 850-nm LEDs in facial recognition modules). |
| Switching Frequency | 1 MHz (typical) - enables use of compact 4.7-μH surface-mount inductors and reduces EMI filter size. |
| FB Reference Voltage | 99 mV ±3 mV - sets LED current accuracy to ±3% with standard 1% sense resistors (e.g., 66 mΩ for 1.5 A). |
| Shutdown Current | 1 μA - preserves battery life in AA/Li-ion–powered portable IR illuminators during standby. |
| Max Duty Cycle | 99% - maintains regulation when VIN approaches VLED + VF, critical for single-LED or low-drop applications. |
| Thermal Shutdown | 165°C with 15°C hysteresis - ensures safe recovery after transient overload without manual reset. |
Pinout & Package
VQFN-HR (6-pin) package: 1.50 mm × 2.00 mm body, 0.4-mm pitch, wettable flank terminals for automated optical inspection (AOI) and improved solder joint reliability in high-volume SMT assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| BOOT | Bootstrap supply | Connects external 0.1-μF X7R ceramic capacitor to SW to generate gate drive voltage for high-side NMOS. |
| FB | Current-sense feedback | Monitors voltage across external RSENSE; device regulates LED current to maintain 99 mV at this pin. |
| GND | Power ground | Common return path for high-side/low-side switches, FB resistor, and thermal pad - must be solid copper pour. |
| DIM | Dimming control input | Accepts either PWM signal (100 Hz–2 kHz) or analog voltage (0.65–1.2 V) to set LED brightness in TPS92200D1 variant. |
| SW | Switching node | Drives external inductor; connects internally to both NMOS drains - requires tight layout to minimize ringing. |
| VIN | Input power supply | Accepts 4–30 V DC; includes 3.5-V UVLO with 0.2-V hysteresis to prevent brownout operation. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated Power Stage | 150-mΩ high-side + 90-mΩ low-side NMOS enables >90% efficiency at 1.5 A with minimal external components. |
| Flexible Dimming Architecture | Hardware-selectable dual-mode interface supports both PWM timing control and analog voltage scaling - no firmware required. |
| Full Fault Recovery | Auto-retry hiccup mode responds to LED open/short, RSENSE fault, or thermal overload with 60-ms off-time and automatic restart. |
| Ultra-Low Quiescent Drain | 1-μA shutdown current allows direct connection to battery without load switch - extends shelf life of portable IR illuminators. |
| Internal Compensation | Eliminates need for external compensation network - reduces BOM count and layout sensitivity in space-constrained designs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LED driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS92200D1DDCR | SOT-23-THIN (6) package; RθJA = 123.4°C/W; same electrical specs and pinout. | Better suited for prototyping or low-power PCBs with limited thermal mass; less suitable for high-ambient or sealed enclosures. | Select DDCR for breadboarding or cost-sensitive low-volume builds where thermal headroom exceeds 25°C. |
| LM3409HVMM/NOPB | Adjustable 1.25-V FB reference; external compensation; 75-V max input; no integrated MOSFETs. | Requires external high-side switch and loop compensation components; supports higher input voltages but larger solution size. | Choose LM3409HVMM/NOPB only when >30-V input or programmable reference is mandatory - not a drop-in replacement. |
Compared with TPS92200D1DDCR, the TPS92200D1RXLR offers superior thermal resistance margin in high-density layouts, while LM3409HVMM/NOPB trades integration for flexibility - making TPS92200D1RXLR optimal for compact, thermally constrained IR illumination designs requiring zero-compensation layout.

FAQ
What dimming modes does the TPS92200D1RXLR support?
The TPS92200D1RXLR supports both PWM dimming (100 Hz–2 kHz digital input) and analog dimming (0.65 V–1.2 V analog voltage input), enabling flicker-free brightness control from 5% to 100%. This dual-mode capability is exclusive to the D1 variant and is confirmed in TI's SLVSER4B datasheet Section 7.4. The TPS92200D1RXLR does not support the deeper 1%–100% analog dimming mode found in D2 variants.
What is the maximum continuous output current of the TPS92200D1RXLR?
The TPS92200D1RXLR delivers 1.5-A continuous LED output current, enabled by its integrated 150-mΩ high-side and 90-mΩ low-side NMOS FETs. This rating is validated across the full –40°C to +125°C junction temperature range and 4–30-V input voltage range per Section 6.5 of the TI SLVSER4B datasheet. Derating is not required below 125°C ambient when using recommended PCB copper area.
Does the TPS92200D1RXLR require external compensation components?
No, the TPS92200D1RXLR features full internal compensation for its peak-current-mode control loop, eliminating the need for external RC networks or type-II/III compensators. This is explicitly stated in Sections 3 and 7.1 of the TI SLVSER4B datasheet and simplifies layout in space-constrained applications such as camera modules. The TPS92200D1RXLR achieves stable regulation with only five external passive components: input/output capacitors, inductor, sense resistor, and bootstrap capacitor.
What protection features are built into the TPS92200D1RXLR?
The TPS92200D1RXLR integrates LED open-load, LED+ short-to-GND, LED+ and LED– short-circuit, sense-resistor open/short-to-GND, and thermal shutdown protections - all with auto-retry hiccup mode. Each fault triggers a 60-ms shutdown followed by automatic restart attempt, as documented in Table 7-1 and Section 7.3.8 of the TI SLVSER4B datasheet. These protections operate independently of external circuitry and require no configuration.
What package type and thermal performance does the TPS92200D1RXLR use?
The TPS92200D1RXLR uses the VQFN-HR (6) package: 1.50 mm × 2.00 mm body, 0.4-mm pitch, with exposed thermal pad. Its junction-to-ambient thermal resistance is 136.1°C/W, and junction-to-board is 49.3°C/W (Section 6.4, TI SLVSER4B). This package provides superior thermal performance over the SOT-23-THIN option in high-power density layouts and supports AOI-compatible reflow profiles.
