Product details
Overview
TPS61160ADRVT from Texas Instruments is a 6-pin WSON white LED boost driver IC with integrated 40-V/0.7-A N-channel MOSFET, 2.7–18 V input range, 26-V open-LED protection, 200-mV ±2% feedback reference, and 600-kHz fixed-frequency PWM control for analog dimming in portable backlighting applications.
For engineers reviewing the TPS61160ADRVT datasheet, TPS61160ADRVT pinout, TPS61160ADRVT application, or TPS61160ADRVT equivalent, this page delivers verified electrical parameters, thermal metrics, PWM dimming behavior, open-LED fault response, and real-world design constraints for mobile display power management.
Technical Context
The TPS61160ADRVT implements current-mode control with internal slope compensation to ensure stability at duty cycles >50%, regulates FB to 200 mV (±2%) for precise LED current setting via external RSET, and uses a dedicated CTRL pin for PWM-based analog dimming without audible capacitor noise.
Its open-LED protection monitors both SW node voltage (26 V threshold) and FB voltage (<100 mV) across eight consecutive switching cycles before disabling the FET; thermal shutdown activates at 160°C with 15°C hysteresis, and undervoltage lockout engages below 2.2 V with 70-mV hysteresis.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.7 V to 18 V - supports single-cell Li-ion (3.0–4.2 V), dual-cell NiMH, or regulated 5/12-V rails without external LDO pre-regulation. |
| Open LED Protection Threshold | 26 V (typical) on SW pin - prevents overvoltage damage when driving up to six 3.3-V white LEDs (19.8 V + 200 mV) plus diode drop. |
| Feedback Reference Voltage | 200 mV ±2% - enables accurate LED current programming with low-power dissipation in RSET (e.g., 10 Ω yields 20 mA). |
| Switching Frequency | 600 kHz (±100 kHz) - allows compact 22-μH inductor and <1-μF output capacitor while minimizing EMI and improving efficiency vs lower frequencies. |
| Quiescent Current | 1.8 mA typical - ensures minimal battery drain during active backlight operation in handheld devices. |
| Shutdown Current | 1 μA max - maintains ultra-low system standby power when CTRL is pulled low for >2.5 ms. |
| Thermal Resistance | RθJA = 140 °C/W (low-K board) - requires thermal pad soldering and ground-plane vias for reliable 85°C ambient operation at full load. |
Pinout & Package
TPS61160ADRVT is housed in a thermally enhanced 2-mm × 2-mm × 0.8-mm WSON-6 package with exposed thermal pad (DRV variant), requiring solder connection to analog ground plane for thermal performance and EMI reduction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| FB (Pin 1) | Current-sense feedback input | Regulated to 200 mV; connects to low-side RSET to set LED current; OLP monitoring point for FB voltage <100 mV. |
| COMP (Pin 2) | Error amplifier output | Drives external compensation network (capacitor only); source/sink capability ±100 μA; crossover frequency ~500 kHz with 5-pF load. |
| GND (Pin 3) | Power and signal ground | Reference for all internal circuits; must be connected to thermal pad and low-impedance PCB ground plane. |
| SW (Pin 4) | Switch node | Connects to inductor and Schottky anode; monitored for 26-V OLP; carries high dv/dt switching waveform. |
| CTRL (Pin 5) | Enable and PWM dimming input | Logic-level enable (VIH ≥1.2 V, VIL ≤0.4 V); accepts 5–100 kHz PWM for analog dimming; 2.5-ms timeout for shutdown. |
| VIN (Pin 6) | Power input | Supplies internal circuitry and switch driver; accepts 2.7–18 V; requires ≥1-μF ceramic input capacitor near pin. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 40-V/0.7-A N-channel MOSFET | Eliminates external high-voltage switch; supports up to six white LEDs in series with margin for forward voltage variation and temperature drift. |
| Built-in soft-start | Ramps FB reference in 32 steps (213 μs each) to limit inrush current; reduces input surge and improves system reliability during power-on. |
| PWM-controlled analog dimming | Modulates internal 200-mV reference via CTRL pin duty cycle - avoids LED current pulsing and eliminates audible capacitor noise. |
| 600-kHz fixed-frequency operation | Enables use of small 22-μH shielded inductors and low-ESR ceramic capacitors; improves transient response and simplifies EMI filtering. |
| Thermal shutdown with hysteresis | Shuts down at 160°C junction temperature and re-enables at 145°C - protects against sustained overload or poor PCB thermal design. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar white LED boost driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS61161ADRVT | 38-V open-LED protection (vs 26 V); identical pinout, package, and control interface. | Supports up to 10-series white LEDs (e.g., 33 V total); requires higher-output-capacitor voltage rating. | Select TPS61161ADRVT when driving >6 LEDs or needing higher OVP margin; otherwise TPS61160ADRVT offers tighter voltage margin for 4–6 LED strings. |
| MAX16832ATA+T | 40-V boost switch, 2.5–28-V input, but uses external MOSFET and requires more external components. | Targeted at industrial LED lighting with programmable dimming and fault reporting; lacks integrated soft-start and OLP comparators. | Choose MAX16832ATA+T for designs requiring adjustable OVP threshold or multi-string support; TPS61160ADRVT provides faster time-to-market for single-string portable backlight. |
Compared with TPS61161ADRVT, the TPS61160ADRVT offers lower OVP threshold for tighter safety margin in 4–6 LED configurations, while MAX16832ATA+T trades integration for flexibility in non-portable systems - making TPS61160ADRVT optimal for space-constrained, battery-powered displays requiring minimal BOM count.

FAQ
What is the maximum number of white LEDs the TPS61160ADRVT can drive in series?
The TPS61160ADRVT supports up to six white LEDs in series, based on its 26-V open-LED protection threshold and typical 3.3-V forward voltage per LED (6 × 3.3 V = 19.8 V), leaving 6.2 V margin for sense resistor drop (200 mV) and diode forward voltage (~0.2 V). Exceeding six LEDs risks triggering OLP during normal operation or temperature-induced Vf drift. The TPS61160ADRVT datasheet confirms this limit in the "Typical Applications" section.
How does PWM dimming work on the TPS61160ADRVT without causing audible noise?
The TPS61160ADRVT implements true analog dimming: the CTRL pin modulates the internal 200-mV feedback reference voltage proportionally to PWM duty cycle, causing the error amplifier to adjust DC LED current continuously - not by pulsing the current itself. This avoids mechanical vibration in output capacitors that occurs with direct PWM current switching. The TPS61160ADRVT achieves this using an internal low-pass filter on the CTRL path, ensuring smooth regulation even at 5–100 kHz dimming frequencies.
What is the recommended inductor value for the TPS61160ADRVT, and why?
Texas Instruments recommends a 22-μH shielded inductor (e.g., TDK VLCF5020T-220MR75-1) for the TPS61160ADRVT. This value balances peak-to-peak ripple current, efficiency (>90% at 20 mA), and stability - especially critical because the TPS61160ADRVT uses current-mode control with fixed slope compensation. Inductors below 10 μH risk loop instability; above 22 μH yield diminishing efficiency returns and larger physical size. The TPS61160ADRVT datasheet specifies 10–22 μH as the validated range.
Does the TPS61160ADRVT require an external compensation network on the COMP pin?
Yes, the TPS61160ADRVT requires an external capacitor (typically 1 nF to 10 nF) from COMP to GND for loop stability. Unlike some drivers with internal compensation, the TPS61160ADRVT's transconductance error amplifier relies on this capacitor to set dominant pole frequency and ensure phase margin >45° across operating conditions. The TPS61160ADRVT datasheet Figure 11 shows the COMP pin connected to a single capacitor; no series resistor is needed unless fine-tuning transient response.
Can the TPS61160ADRVT operate from a 3.0-V input and still drive six LEDs reliably?
Yes, the TPS61160ADRVT supports 3.0-V minimum input and can reliably drive six white LEDs (total Vf ≈ 19.8 V) due to its 40-V rated internal switch and 600-kHz switching frequency enabling efficient energy transfer with small passive components. At 3.0 V input, the required duty cycle is ~85%, which remains within the TPS61160ADRVT's 93% maximum spec. Efficiency drops to ~82% (per Figure 2), but thermal performance remains acceptable with proper PCB layout and thermal pad connection.
