Product details
Overview
TPS610993YFFR from Texas Instruments is a synchronous boost converter optimized for ultra-low-power battery systems, delivering fixed 3.0V output with 2.94–3.06V accuracy, 0.7–5.5V input range, and 600nA quiescent current into VOUT. It supports down mode regulation and true shutdown disconnection, enabling long runtime in optical heart rate monitors and memory LCD bias circuits.
For engineers reviewing the TPS610993YFFR datasheet, TPS610993YFFR pinout, TPS610993YFFR application, or TPS610993YFFR equivalent, key selection criteria include fixed 3.0V output tolerance, 0.8A peak switch current limit, hysteretic control topology, WCSP package thermal performance, and compatibility with coin-cell and alkaline battery inputs.
Technical Context
The TPS610993YFFR implements a hysteretic current-mode control architecture that dynamically adjusts switching frequency based on VIN, VOUT, and inductor value-enabling discontinuous conduction at light loads to sustain up to 75% efficiency at 10µA. Its down mode maintains regulated 3.0V output even when VIN exceeds VOUT, while pass-through operation engages when VIN > VOUT + 0.5V.
True shutdown disconnects load from input via full PMOS gate control, limiting shutdown current to ≤1.6µA. Overvoltage protection triggers at 5.6–6.0V with 100–200mV hysteresis, and thermal shutdown activates at 150°C with 25°C hysteresis-both critical for unattended wearable deployments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output voltage | Fixed 3.0V (2.94–3.06V accuracy in PWM mode), eliminating external feedback resistors |
| Input voltage range | 0.7V to 5.5V-supports single alkaline, NiMH, Li-Mn, or Li-ion cells without pre-regulation |
| Quiescent current | 400nA into VIN / 600nA into VOUT-enables multi-year operation from coin-cell batteries |
| Peak switch current limit | 0.8–1.25A (≥0.8A minimum)-supports ≥300mA output at 3.3V→5V conversion |
| Efficiency | Up to 75% at 10µA load; up to 93% at 10–300mA-optimized for intermittent sensor bursts |
| Control topology | Hysteretic current-mode-no external compensation required; self-adjusting frequency reduces EMI risk |
| Protection features | UVLO (0.6V rising threshold), OVP (5.6–6.0V), thermal shutdown (150°C), and short-circuit current limiting |
Pinout & Package
TPS610993YFFR uses a 6-ball, 1.23mm × 0.88mm DSBGA (WCSP) package with bottom-side thermal pad connected to GND. The compact footprint enables integration into space-constrained wearables and medical patches.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | Power input | Accepts 0.7–5.5V source; connects to input capacitor and battery anode |
| SW | Switch node | Drives external 2.2µH inductor; high dv/dt node requiring tight layout and ground shielding |
| EN | Enable logic input | Active-high control (VIH ≥1.2V); must be pulled low or grounded to achieve true shutdown |
| GND | Power ground | Reference for all internal circuitry; connects to thermal pad and PCB ground plane |
| VOUT | Regulated output | Delivers fixed 3.0V; supplies load directly-no FB connection needed for this variant |
| FB | Feedback input | Internally tied to reference for fixed-output versions; must be connected to GND per datasheet guidance |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low IQ operation | 400nA into VIN ensures <1µA system standby current-critical for always-on optical sensors |
| Down mode regulation | Maintains stable 3.0V output even when VIN rises above 3.0V (e.g., fresh alkaline cell), avoiding LDO post-regulation |
| True shutdown disconnection | Breaks input-to-output path completely, reducing leakage to ≤1.6µA-enables zero-power sleep states |
| Integrated OVP and thermal protection | 5.6–6.0V overvoltage cutoff and 150°C thermal shutdown prevent field failures in sealed enclosures |
| Hysteretic control | Eliminates need for external compensation network-reduces BOM count and layout sensitivity |

Equivalent & Alternatives
The following parts are listed as comparable options for similar boost converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS610994YFFR | Fixed 3.3V output (3.23–3.37V), identical package and quiescent current specs | Requires redesign of downstream 3.3V-tolerant circuitry; not drop-in for 3.0V logic rails | Select only if system voltage margin allows 3.3V operation and no level-shifting is needed |
| TPS610996YFFR | Fixed 4.5V output (4.4–4.6V), same thermal and electrical characteristics except VOUT | Suitable for higher-voltage analog front-ends (e.g., ADC references, op-amp rails) but incompatible with 3.0V microcontrollers | Choose when powering mixed-signal subsystems needing 4.5V bias without external LDOs |
Compared with TPS610993YFFR, TPS610994YFFR and TPS610996YFFR share identical ultra-low IQ, down mode, and WCSP packaging-but differ solely in factory-programmed output voltage, requiring careful validation of downstream voltage tolerances before substitution.

FAQ
What is the output voltage tolerance of TPS610993YFFR under PWM mode?
The TPS610993YFFR delivers a fixed 3.0V output with ±2% accuracy (2.94V to 3.06V) when operating in PWM mode across –40°C to 125°C junction temperature. This specification is validated per TI's SLVSD88M datasheet Section 6.5 and applies to all production units regardless of input voltage within the 0.7–5.5V range.
Does TPS610993YFFR require external feedback resistors to set its output voltage?
No, TPS610993YFFR does not require external feedback resistors. As a fixed-output variant, its 3.0V regulation is factory-programmed via internal EEPROM; the FB pin must be connected to GND per TI's recommended configuration for fixed-output versions.
How does TPS610993YFFR behave when input voltage exceeds 3.0V?
When VIN rises above 3.0V, TPS610993YFFR automatically enters down mode to maintain regulated 3.0V output until VIN reaches VOUT + 0.5V (i.e., 3.5V), then transitions to pass-through mode where VOUT follows VIN minus losses. This behavior is intrinsic to the device's control architecture and requires no external circuitry.
What is the maximum continuous output current supported by TPS610993YFFR?
TPS610993YFFR supports up to 300mA continuous output current when converting from 3.3V to 5V, achieving up to 93% efficiency at 200mA load. The 0.8A minimum peak switch current limit ensures robust transient response, though sustained current depends on thermal design and PCB copper area.
Can TPS610993YFFR operate from a single 1.5V alkaline cell?
Yes, TPS610993YFFR operates from as low as 0.7V input, making it fully compatible with single 1.5V alkaline cells-even as they discharge below 1.0V. Its ability to start up with 0.7V input and >3kΩ load enables multi-year operation in low-duty-cycle applications like periodic sensor readings.
