Product details
Overview
TPS61301YFFR from Texas Instruments is a 1.5-A/4.1-A multiple LED camera flash driver IC with I²C interface, synchronous boost topology, and integrated constant-current sinks for up to three white LEDs. It supports DC light (400 mA/800 mA/400 mA) and flash modes (up to 1025 mA/2050 mA/1025 mA), operates from 2.5 V–5.5 V input, and delivers regulated output up to 5.7 V - designed for smartphone camera flash power management.
For engineers reviewing the TPS61301YFFR datasheet, TPS61301YFFR pinout, TPS61301YFFR application, or TPS61301YFFR equivalent, key selection criteria include hardware reset (NRESET) support, HC_SEL-configurable current modes, FLASH_SYNC zero-latency strobe triggering, and DSBGA-20 package compatibility with ≤25 mm² total solution size.
Technical Context
The TPS61301YFFR implements a high-frequency (1.92 MHz) synchronous boost converter with three independent constant-current LED sinks and dual-mode operation: voltage-regulated boost (3.8 V–5.7 V) and current-regulated flash/DC light. Its architecture includes automatic VF/ESR calibration, storage-capacitor-friendly energy delivery, and power-save mode enabling >95% peak efficiency.
It integrates hardware control inputs including NRESET (active-low master reset), HC_SEL (high-current mode selection), FLASH_SYNC (zero-latency strobe trigger), and Tx-MASK (RF PA synchronization), all operating at I²C-compatible logic levels with 3.4 Mbps max clock rate. The device maintains output regulation even when input voltage exceeds nominal VOUT.

FAQ
What is the primary function of the NRESET pin on the TPS61301YFFR?
The NRESET pin on the TPS61301YFFR is an active-low hardware reset input that forces the device into shutdown mode and resets the I²C interface state. When pulled low, it immediately disables all LED current sinks, halts switching, and clears internal registers - providing deterministic recovery from fault conditions. This feature distinguishes TPS61301YFFR from TPS61300YFFR and is essential for robust power sequencing in smartphone camera subsystems.
How does the HC_SEL pin affect LED current capability in the TPS61301YFFR?
The HC_SEL pin on the TPS61301YFFR selects between two operational modes: when LOW, it configures the device for direct-drive flash mode (400 mA/800 mA/400 mA max per LED channel); when HIGH, it enables extended high-current mode using storage capacitor discharge (1025 mA/2050 mA/1025 mA). This pin must be actively driven - floating is prohibited - and determines both peak current limits and internal power-stage behavior.
Does the TPS61301YFFR support I²C communication at speeds above standard mode?
Yes, the TPS61301YFFR supports I²C communication up to 3.4 Mbps in High-Speed Mode, in addition to Standard (100 kHz) and Fast (400 kHz) modes. This enables rapid register writes for dynamic flash intensity adjustment and status reads during burst capture sequences. The SCL and SDA pins meet JEDEC HS-mode timing requirements with specified rise/fall times and capacitive load limits up to 400 pF.
What is the role of the FLASH_SYNC pin in TPS61301YFFR timing-critical applications?
The FLASH_SYNC pin on the TPS61301YFFR provides zero-latency strobe synchronization: a rising edge instantly transitions the LED current from DC light level to programmed flashlight level without software or I²C delay. This hardware-triggered response - with 400 µs (HC_SEL = LOW) or 16 µs (HC_SEL = HIGH) settling time - ensures pixel-perfect alignment between LED illumination and camera sensor exposure, critical for high-speed photography.
Can the TPS61301YFFR operate as a standard voltage regulator, not just an LED driver?
Yes, the TPS61301YFFR operates as a regulated voltage boost converter (3.8 V–5.7 V) in addition to its LED current-sink function. When configured via ENVM pin or I²C register, it regulates VOUT to a fixed 4.95 V with ±2% accuracy, maintaining regulation even if input voltage exceeds output voltage. This dual-mode capability allows reuse of the same IC for flash power and auxiliary rails like audio amplifier supplies.
