Product details
Overview
TPS61300YFFT from Texas Instruments is a 20-pin DSBGA synchronous boost LED flash driver IC for smartphone camera modules, supporting up to three white LEDs with 400 mA / 800 mA / 400 mA flash current (HC_SEL = LOW), 2 MHz switching frequency, 400 mV LED sense voltage, and I²C interface up to 3.4 Mbps. It operates in DC light, flashlight, voltage regulation (3.8–5.7 V), and standby (2 µA) modes.
For engineers reviewing the TPS61300YFFT datasheet, TPS61300YFFT pinout, TPS61300YFFT application, or TPS61300YFFT equivalent, key selection criteria include its hardware-controlled ENDCL input for DC light mode, FLASH_SYNC zero-latency strobe synchronization, storage-capacitor-friendly energy management, and integrated privacy indicator (INDLED) output - all within a <25 mm² total solution size.
Technical Context
The TPS61300YFFT implements a high-frequency synchronous boost converter with three independent constant-current sinks and a dedicated INDLED constant-current source. Its dual-mode operation-regulated current sink for LED drive and regulated voltage boost for auxiliary rails-is managed via I²C registers and hardware pins (ENDCL, HC_SEL, FLASH_SYNC).
It features automatic VF/ESR calibration, power-save mode enabling >95% efficiency at light loads, and active cell balancing for supercapacitor-based flash energy storage. The device maintains output voltage regulation even when input exceeds nominal VOUT, and supports Tx-MASK–triggered instantaneous LED current reduction for RF coexistence.

Equivalent & Alternatives
The following parts are listed as comparable options for similar LED flash driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS61301YFFT | Includes NRESET pin (not present on TPS61300); identical flash/current specs and pinout; adds hardware reset capability. | Required where system-level hardware reset coordination with flash subsystem is needed (e.g., camera module power sequencing). | Choose TPS61301YFFT if NRESET functionality is required; otherwise TPS61300YFFT offers identical flash performance with simpler enable control (ENDCL only). |
| TPS61306YFFT | Includes both ENDCL and TS (temperature sense) pins; same flash current ratings and DSBGA package; adds LED thermal monitoring. | Suitable for thermally constrained designs requiring closed-loop LED temperature protection (e.g., sealed camera modules). | Choose TPS61306YFFT when LED junction temperature monitoring is mandatory; TPS61300YFFT omits TS and is optimized for cost-sensitive, non-thermal-critical implementations. |
Compared with TPS61301YFFT and TPS61306YFFT, the TPS61300YFFT provides the leanest feature set-retaining core flash/DC light functionality and ENDCL control while excluding NRESET and TS-making it optimal for cost-driven, thermally stable smartphone camera designs where those features are unnecessary.

FAQ
What is the primary function of the TPS61300YFFT in a mobile camera system?
The TPS61300YFFT serves as a highly integrated synchronous boost LED flash driver IC, delivering precise constant-current drive to up to three white LEDs for still-image flash and continuous DC light (video torch) modes. It integrates I²C control, hardware strobe synchronization (FLASH_SYNC), DC light enable (ENDCL), and privacy indicator drive (INDLED), all in a 1.90 mm × 2.20 mm DSBGA package. Its design targets minimal solution size (<25 mm²) and low quiescent current (2 µA standby) for battery-powered smartphones.
Does the TPS61300YFFT support hardware reset, and how does it differ from TPS61301YFFT?
No, the TPS61300YFFT does not include a hardware reset pin. The TPS61301YFFT adds the NRESET input, which forces the device into shutdown and resets the I²C interface when pulled low. This makes TPS61301YFFT suitable for systems requiring coordinated power sequencing or fault recovery, whereas TPS61300YFFT relies solely on I²C commands and ENDCL for mode control - simplifying layout and reducing external component count where NRESET is unnecessary.
How does the FLASH_SYNC pin improve camera system timing performance?
The FLASH_SYNC pin on the TPS61300YFFT provides zero-latency hardware triggering: asserting HIGH immediately transitions the device from DC light to full-flash current (e.g., 800 mA → 1850 mA on LED2) with ≤16 µs settling time (HC_SEL = HIGH). This eliminates software/I²C latency, ensuring LED illumination precisely aligns with mechanical or electronic shutter actuation - critical for eliminating motion blur and achieving consistent exposure in high-speed capture.
Can the TPS61300YFFT drive a privacy indicator LED, and what are its specifications?
Yes, the TPS61300YFFT includes a dedicated INDLED pin that provides a programmable constant-current source (2.6–7.9 mA typical) for driving low-forward-voltage privacy indicator LEDs. It operates independently of the main LED channels and supports temperature coefficient of 0.04 %/°C, enabling robust optical feedback aligned with camera activation state - a key requirement for regulatory-compliant privacy signaling in laptops, tablets, and smart displays.
What is the role of the HC_SEL pin, and how does it affect LED current capability?
The HC_SEL pin on the TPS61300YFFT selects between two flash operating modes: LOW enables direct LED drive (400 mA / 800 mA / 400 mA max for LED1/LED2/LED3), while HIGH activates energy-storage mode using a supercapacitor, raising peak currents to 925 mA / 1850 mA / 925 mA. This pin must be terminated (not left floating) and determines whether the device prioritizes low-latency response (HC_SEL = LOW) or maximum flash intensity (HC_SEL = HIGH), directly impacting capacitor sizing and thermal design.
