Product details
Overview
TPS610995YFFR from Texas Instruments is a synchronous boost converter optimized for ultra-low-power battery systems, delivering 3.6V fixed output with 600nA quiescent current into VOUT and 400nA into VIN, operating from 0.7V–5.5V input, and supporting true load disconnection during shutdown - ideal for optical heart rate monitor LED bias and memory LCD applications.
For engineers reviewing the TPS610995YFFR datasheet, TPS610995YFFR pinout, TPS610995YFFR application, or TPS610995YFFR equivalent, key selection criteria include its 3.6V fixed output accuracy (±3%), hysteretic control topology, down-mode regulation capability, and 1.23mm × 0.88mm WCSP package suitability for space-constrained wearable designs.
Technical Context
The TPS610995YFFR implements a hysteretic current-mode control architecture that dynamically adjusts switching frequency to maintain high efficiency across 10µA–300mA loads, enabling burst-mode operation under light loads and seamless transition between boost, down, and pass-through modes based on VIN–VOUT differential. Its internal feedback reference is trimmed to 1.00V ±2% and supports down-mode regulation when VIN exceeds VOUT by as little as 50mV.
It integrates cycle-by-cycle overcurrent protection with 0.8A minimum peak switch current limit, thermal shutdown at 150°C (25°C hysteresis), and output overvoltage protection at 5.8V. The device achieves up to 75% efficiency at 10µA load and up to 93% at 200mA, leveraging synchronous rectification with low RDS(on) switches (≤350mΩ HS, ≤300mΩ LS at VOUT = 3.3V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output voltage | Fixed 3.6V ±3% (PWM mode), ensures stable bias for precision analog sensors without external resistor divider |
| Quiescent current (VIN) | 400nA typical - enables multi-year operation from coin-cell batteries in always-on wearable monitoring |
| Quiescent current (VOUT) | 600nA typical - minimizes standby loss in systems where VOUT powers low-leakage analog circuitry |
| Input voltage range | 0.7V–5.5V - supports direct operation from single alkaline, NiMH, or Li-Mn cells down to end-of-life voltage |
| Peak switch current limit | 0.8A minimum - sustains regulated 3.6V output up to ~250mA load while maintaining down-mode stability |
| Efficiency @ 10µA | Up to 75% - critical for extending runtime in ultra-low-duty-cycle applications like optical HRM sampling |
| Package | 6-ball DSBGA (YFF), 1.23mm × 0.88mm - enables <1.1mm² PCB footprint for compact wearables |
Pinout & Package
TPS610995YFFR uses a 6-ball, 1.23mm × 0.88mm DSBGA (WCSP) package with bottom-side solder balls. Thermal performance is enhanced via PowerPAD™ connected to GND.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | Power input | Accepts 0.7V–5.5V supply; connects to input capacitor and battery anode; UVLO activates below 0.6V |
| SW | Switch node | Drives external 2.2µH inductor; carries pulsed current up to 0.8A peak; requires low-ESR ceramic output cap |
| EN | Enable logic input | Active-high control: ≥1.2V enables, ≤0.4V disables; true shutdown disconnects VOUT from VIN |
| GND | Power ground | Reference for all internal circuits; must be low-impedance connection to PowerPAD™ and input/output caps |
| VOUT | Regulated output | Delivers fixed 3.6V; supplies load directly; internal feedback network eliminates need for FB resistor divider |
| FB | Feedback input | Internally tied to GND for fixed-output versions; left unconnected in TPS610995YFFR (no external divider required) |
Key Features
| Feature | Design Value |
|---|---|
| Hysteretic current-mode control | Enables variable-frequency operation that maximizes efficiency at microamp loads without external compensation |
| Down-mode regulation | Maintains 3.6V output even when VIN rises above 3.6V (e.g., fresh Li-ion cell), eliminating need for LDO post-regulation |
| True shutdown disconnection | Reduces total system standby current to <500nA by fully isolating VOUT from VIN via PMOS gate control |
| Burst-mode operation | Extends battery life in intermittent-sensing applications by reducing average IQ to sub-100nA during idle periods |
| Integrated OVP & thermal protection | Shuts down at 5.8V output or 150°C junction temperature, then auto-recovers - prevents field failures in sealed wearables |
Applications

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS610994YFFR | Fixed 3.3V output; identical quiescent current, package, and control architecture | Suitable for 3.3V I/O domains or lower-voltage sensors requiring tighter regulation margin | Select when system logic or analog front-end operates natively at 3.3V and higher output voltage introduces unnecessary headroom loss |
| TPS610996YFFR | Fixed 4.5V output; same pinout and thermal specs; 100mV higher VREF tolerance (±2.2% vs ±3%) | Preferred for applications needing higher bias voltage for white LED strings or legacy 4.5V analog rails | Choose when output must exceed 3.6V and system can tolerate slightly higher light-load IQ (0.45µA vs 0.4µA into VIN) |

FAQ
What is the output voltage tolerance of the TPS610995YFFR under varying load and temperature conditions?
The TPS610995YFFR delivers a fixed 3.6V output with ±3% accuracy in PWM mode across –40°C to 125°C junction temperature and full load range. Measured output variation remains within 3.53V–3.67V at 25°C and 3.53V–3.71V in PFM mode, ensuring reliable bias for precision analog circuits without external trimming.
Does the TPS610995YFFR require external feedback resistors to set its output voltage?
No, the TPS610995YFFR does not require external feedback resistors. It is a fixed-output variant with internal resistor divider and EEPROM-trimmed reference; the FB pin is internally connected to GND. This eliminates two passive components, saves PCB area, and improves long-term stability versus discrete resistor networks.
How does the TPS610995YFFR behave when input voltage exceeds 3.6V?
When VIN rises above VOUT, the TPS610995YFFR automatically enters down-mode regulation to maintain 3.6V output until VIN reaches VOUT + 0.5V (≈4.1V), then transitions to pass-through mode where VOUT follows VIN minus inductor DCR and PMOS RDS(on) drop - enabling efficient operation across full Li-ion voltage range without external regulators.
What is the minimum input voltage required for the TPS610995YFFR to start up and regulate?
The TPS610995YFFR starts up reliably from 0.7V input with a load impedance greater than 3kΩ. Startup succeeds even at 0.7V if output capacitance is ≥10µF and initial load current is ≤100µA; heavier loads may require VIN ≥1.2V to reach 1.6V soft-start threshold before entering hysteretic regulation.
Can the TPS610995YFFR be used in applications requiring true load disconnection during shutdown?
Yes, the TPS610995YFFR provides true shutdown disconnection: when EN is pulled low, both high-side and low-side switches turn off and the internal PMOS rectifier gate is actively driven to isolate VOUT from VIN, reducing total shutdown current to <500nA and preventing battery drain through parasitic paths in always-connected systems.
