Product details
Overview
TPS61310YFFR from Texas Instruments is a 1.5-A synchronous boost LED flash and video light driver with I²C interface, supporting up to three white LEDs in parallel. It operates from 2.5 V to 5.5 V input, delivers regulated LED current up to 950 mA on LED2 (typical), and integrates temperature monitoring, open/short LED protection, and a 2-MHz switching frequency for compact 2.2-µH inductor use - deployed in smartphone camera modules for flash strobe and continuous video lighting.
For engineers reviewing the TPS61310YFFR datasheet, TPS61310YFFR pinout, TPS61310YFFR application, or TPS61310YFFR equivalent, key selection criteria include its 20-pin DSBGA package, I²C-compatible interface up to 3.4 Mbps, dual strobe control (STRB0/STRB1), integrated NTC-based thermal sensing via TS pin, and hardware reset (NRESET) for system-level fault recovery.
Technical Context
The TPS61310YFFR implements a synchronous boost converter topology with three independent current-sink channels (LED1, LED2, LED3) and a dedicated privacy indicator output (INDLED). Its control logic supports concurrent video light (low-current, sustained) and flash strobe (high-current, pulsed) modes, with zero-latency turn-on via STRB0 and RF PA synchronization via Tx-MASK.
It features adaptive output voltage regulation (3.825 V to 5.7 V), power-save mode for >95% efficiency at light loads, and integrated safety functions including LED safety timer, battery droop detection, and smooth current ramp-up/down. The device uses a 400-mV internal current-sense reference and supports I²C register configuration of LED current, timing, and thermal thresholds.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.5 V to 5.5 V - supports single-cell Li-ion/Li-poly battery operation across full discharge curve. |
| Max LED Current (LED2) | 950 mA - enables high-brightness flash strobe for smartphone still-camera applications. |
| Switching Frequency | 2 MHz - allows use of low-profile 2.2-µH inductors and reduces EMI filtering requirements. |
| I²C Interface Speed | Up to 3.4 Mbps (high-speed mode) - enables fast LED current reconfiguration during video capture transitions. |
| Thermal Protection | 140°C shutdown with 20°C hysteresis - prevents thermal runaway during sustained video light operation. |
| Quiescent Current | 590 µA typical - minimizes standby power draw in always-on camera subsystems. |
| Package | 20-pin NanoFree™ DSBGA (2.20 mm × 1.90 mm) - ultra-compact footprint for space-constrained mobile PCBs. |
Pinout & Package
TPS61310YFFR is housed in a 20-pin NanoFree™ DSBGA (YFF) package measuring 2.20 mm × 1.90 mm, with bottom-side ball layout optimized for minimal PCB area and thermal performance. The package uses copper pillar interconnects and requires standard BGA assembly processes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VOUT | Boost converter output | Regulated DC voltage node (3.825–5.7 V) supplying LED anodes and external circuitry. |
| AVIN | Analog input supply | Main power input (2.5–5.5 V); connects directly to bypass capacitor for analog rail stability. |
| SW | Switch node | Drain of internal high-side MOSFET; connects to inductor switch node and requires low-inductance routing. |
| LED1 / LED2 / LED3 | Current-sink feedback inputs | Connect to LED cathodes; regulate current via 400-mV internal sense reference. |
| PGND / AGND | Power and analog ground | Separate ground planes required; PGND handles high di/dt switching return, AGND serves precision analog circuits. |
| SDA / SCL | I²C bidirectional data/clock | Supports standard/fast/high-speed modes; require external pull-ups per bus capacitance (≤400 pF). |
| NRESET | Hardware reset input | Active-low asynchronous reset; forces shutdown and clears I²C registers when pulled low ≥10 µs. |
| STRB0 / STRB1 | Strobe enable and mode select | STRB0 enables/disables all LEDs; STRB1 selects flash (LOW) vs video light (HIGH) mode. |
| TS | NTC temperature sense input | Bias current source (23.8 µA) for 220-kΩ NTC; detects LED junction temperature for thermal derating. |
| INDLED | Privacy indicator current source | Constant-current sink (2.6–15.8 mA) for low-VF status LED; independent of main LED drivers. |
| GPIO/PG | Configurable I/O or power-good | Default open-drain PG output signals VOUT regulation status; configurable as GPIO via I²C. |
| Tx-MASK | RF PA synchronization input | Pull HIGH to instantly reduce LED current from flash to video level, minimizing battery peak load during TX. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-mode LED control | Hardware-selectable flash strobe (STRB1 = LOW) or video light (STRB1 = HIGH) with zero-latency turn-on via STRB0. |
| Integrated thermal management | TS pin with 23.8-µA bias current enables precise NTC-based LED temperature monitoring and automatic current derating. |
| Robust fault protection | Detects open/shorted LEDs, enforces integrated safety timer, monitors battery droop, and provides undervoltage lockout (2.3–2.4 V). |
| High-efficiency power-save mode | Maintains >95% efficiency at light loads by automatically entering PFM/PWM hybrid operation without external control. |
| Compact total solution size | Full implementation occupies <25 mm² PCB area using 2.2-µH inductor, 10-µF and 4.7-µF output capacitors, and DSBGA package. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LED flash and video light driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS61311YFFR | Higher input valley current limit (2480 mA vs 1750 mA); identical pinout and feature set. | Supports higher peak LED currents (up to ~1.2 A on LED2) for larger optical modules or multi-die LEDs. | Select TPS61311YFFR when >950 mA LED2 current or higher input current headroom is required; otherwise TPS61310YFFR suffices for mainstream smartphones. |
| LM3644YFQR | 2.5-A dual-channel flash driver; lacks INDLED output, TS-based thermal monitoring, and Tx-MASK input. | Focused on flash-only applications; no native video light mode or RF synchronization capability. | Choose LM3644YFQR only for cost-sensitive flash-only designs where video lighting and thermal safety are not required. |
Compared with TPS61310YFFR, TPS61311YFFR offers higher current capability in identical packaging, while LM3644YFQR provides simpler flash control but omits critical video-light and thermal-safety features - making TPS61310YFFR the balanced choice for dual-mode mobile camera systems requiring reliability and regulatory compliance.

FAQ
What is the maximum LED current supported by TPS61310YFFR on the LED2 channel?
The TPS61310YFFR supports up to 950 mA (typical) on the LED2 channel under recommended operating conditions. This value is verified in the Electrical Characteristics table for LED2 current accuracy at 85°C and full-scale operation. The actual achievable current depends on input voltage, thermal conditions, and inductor selection - with peak capability limited by the 1750-mA input valley current specification.
Does TPS61310YFFR support both flash strobe and continuous video light modes?
Yes, TPS61310YFFR natively supports both modes via hardware pins: STRB1 = LOW enables flash strobe mode with high-current pulse capability, while STRB1 = HIGH activates video light mode with lower sustained current and watchdog timer disable. STRB0 provides zero-latency enable/disable control for both modes, and Tx-MASK allows instantaneous flash-to-video transition during RF transmission.
How does the TS pin function for thermal monitoring in TPS61310YFFR?
The TS pin on TPS61310YFFR sources a precise 23.8-µA current for biasing an external 220-kΩ NTC thermistor. Resistance changes at the TS pin are interpreted internally to detect warning (39–50 kΩ) and hot (12.5–16.5 kΩ) temperature thresholds, triggering automatic LED current derating or shutdown. If unused, TS must be tied to AVIN or left floating - not grounded.
What is the purpose of the INDLED pin on TPS61310YFFR?
The INDLED pin on TPS61310YFFR provides a dedicated constant-current sink (2.6–15.8 mA) for driving a low-forward-voltage privacy indicator LED. It operates independently of the main LED1–LED3 channels and is controlled via I²C registers, enabling visual confirmation of camera/microphone activity without affecting flash or video lighting performance.
Is TPS61310YFFR pin-compatible with TPS61311YFFR?
Yes, TPS61310YFFR and TPS61311YFFR share identical 20-pin DSBGA (YFF) packaging, pinout, and register map. The only functional difference is the higher input valley current limit (2480 mA vs 1750 mA) in TPS61311YFFR, which enables greater peak LED current capability - making them drop-in replacements where thermal and electrical margins allow.
