Typical Applications
TPS61160DRVR is suitable for 6 applications: Smartphone / Tablet LCD Backlighting, Portable Battery-Powered Devices, Portable Navigation and Handheld Displays, Constant-Current LED Indicators and Task Lighting, Automotive Infotainment Display Backlight (non-safety), E-reader and Instrument Panel Lighting.
Smartphone / Tablet LCD Backlighting
The TPS61160DRVR is purpose-built for small-panel backlighting: the 2x2-mm WSON-6 package fits the tight board area behind a phone display, and the 700-mA switch limit drives a string of up to 10 series white LEDs at typical 15-20 mA. The 600-kHz fixed frequency keeps ripple and inductor size small, while 200-mV feedback limits sense-resistor loss for battery-run efficiency. Single-wire digital dimming on the CTRL pin enables stepless brightness from the application processor without extra pins or an external DAC.
Recommended
Portable Battery-Powered Devices
With a 2.7-V minimum input, the TPS61160DRVR operates through the full discharge range of a single Li-ion cell (2.7-4.2 V) and accepts multi-cell alkaline or NiMH stacks up to 18 V. The integrated 40-V switch FET removes the external MOSFET from the BOM, and PWM dimming lets firmware scale backlight current to extend battery life. The 93% maximum duty cycle sustains regulation even when the battery is low and the boost ratio is highest.
Recommended
Portable Navigation and Handheld Displays
Handheld GPS and navigation units need bright, uniform backlights from a 3.7-V Li-ion battery. The TPS61160DRVR boosts the battery to the LED-string voltage while the 26-V open-LED protection prevents output overvoltage if a connector opens or an LED fails. Open-circuit protection is critical in handheld devices where the display flex cable is repeatedly mated; the clamp protects the 40-V internal switch and surrounding components from damaging voltage spikes.
Recommended
Constant-Current LED Indicators and Task Lighting
Beyond LCD backlighting, the TPS61160DRVR works as a general constant-current boost LED driver for 12-V-rail indicator or small task-light applications. Setting LED current via I_LED = 200 mV / R_sense gives accurate, thermally stable current, and PWM input dimming supports human-eye-smooth brightness control. The -40 to +85 C operating range covers industrial enclosures, and the fixed 600-kHz switching frequency places EMI harmonics where standard input filters are effective.
Recommended
Automotive Infotainment Display Backlight (non-safety)
The 18-V input range tolerates automotive 12-V board-net transients, allowing the TPS61160DRVR to drive backlight strings for secondary displays such as cluster sub-panels or control knobs. PWM dimming synchronizes with display refresh to eliminate visible flicker, and the 600-kHz frequency eases conducted-emissions compliance. Note the standard TPS61160DRVR is rated -40 to +85 C and is not AEC-Q100 qualified; for qualified designs, verify TI automotive-status alternatives before release.
Recommended
E-reader and Instrument Panel Lighting
E-readers and front-lit instrument panels use a series LED string at low current where efficiency and flicker-free dimming dominate. The TPS61160DRVR's single-wire digital dimming integrates an incoming PWM duty cycle into stepless brightness, avoiding audible-frequency artifacts and enabling smooth night-mode transitions. Small external components (a compact inductor at 600 kHz, 10-uF ceramics) keep the driver area minimal, and thermal shutdown plus open-LED protection provide robust fault behavior.

Key Differentiators
- Higher open-LED clamp headroom with TPS61161 (vs TPS61161DRVR)
- Integrated 40-V switch FET (vs TPS61291DRVR)
- Dual dimming flexibility (vs TPS61160ADRVR)
Design Notes
Keep the boost power loop (VIN, inductor, SW pin, output capacitor, ground return) as short and tight as possible. Place the input capacitor within 2-3 mm of VIN and the output diode close to SW. Solder the exposed thermal pad to a grounded copper pour with at least 4-6 vias to the ground plane; this pad is the primary heat path for the 2x2-mm WSON-6 package. Follow the layout section of the TI TPS61160 datasheet.
Verify the sum of LED forward voltages at worst-case low temperature stays below the 26-V open-LED clamp; white LED Vf rises roughly 2-3 mV per degree C as temperature falls, and hitting the clamp during startup looks like a fault. Also size the sense resistor from I_LED = 200 mV / R_sense with 1% tolerance, and do not omit the output capacitor or the control loop may become unstable at light load.
At 700-mA switch current and low battery input, switch and inductor losses concentrate in the small WSON-6 die. Estimate junction rise using the package thermal resistance and derail operation above the -40 to +85 C range limit. In dense handheld layouts, add thermal vias under the EP and keep nearby hot components (buck converters, chargers) at least 5 mm away; LED brightness calibration should be done at operating temperature because LED Vf shifts with heat.
