Product details
Overview
TPS610993YFFT from Texas Instruments is a synchronous boost converter optimized for ultra-low-power battery-powered systems, delivering fixed 3.0V output with 600nA quiescent current into VOUT, 400nA into VIN, 0.7V–5.5V input range, and true load disconnection during shutdown - ideal for optical heart rate monitor LED bias and memory LCD applications.
For engineers reviewing the TPS610993YFFT datasheet, TPS610993YFFT pinout, TPS610993YFFT application, or TPS610993YFFT equivalent, key selection criteria include its 3.0V fixed output accuracy (±2%), 0.8A peak switch current limit, hysteretic control topology enabling 75% efficiency at 10µA load, and WCSP package compatibility with space-constrained wearable designs.
Technical Context
The TPS610993YFFT implements a hysteretic current-mode control architecture that dynamically adjusts switching frequency based on input voltage, output voltage, and inductor value - eliminating external compensation while maintaining regulation across 0.7V–5.5V input and down to 10µA loads. It supports three operational modes: boost (VIN < VOUT), down mode (VIN > VOUT but ≤ VOUT + 0.5V), and pass-through (VIN > VOUT + 0.5V), with automatic transitions governed by internal thresholds.
Its integrated protection suite includes cycle-by-cycle overcurrent limiting (0.8A min), output overvoltage protection (5.8V threshold), undervoltage lockout (0.7V rising, 200mV hysteresis), thermal shutdown (150°C), and true shutdown with <0.5µA VIN leakage - all enabled without external components. The FB pin is internally tied to GND for fixed-output operation, removing need for external resistor divider.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.0V ±2% - eliminates external feedback resistors and reduces BOM count in compact designs. |
| Quiescent Current (VIN) | 400nA - enables multi-year battery life in coin-cell or alkaline-powered devices operating at microamp loads. |
| Quiescent Current (VOUT) | 600nA - maintains ultra-low standby power even when output is loaded, critical for always-on sensor nodes. |
| Input Voltage Range | 0.7V to 5.5V - supports single-cell Li-ion (2.7–4.2V), NiMH (0.9–1.4V), alkaline (0.7–1.5V), and Li-Mn (2.0–3.6V) batteries without pre-regulation. |
| Peak Switch Current Limit | 0.8A minimum - sustains regulated 3.0V output up to ~300mA load under typical conditions, supporting LED bias and low-power RF transceivers. |
| Efficiency @ 10µA Load | Up to 75% - maximizes usable energy from depleted batteries where conventional boost converters fail. |
| Shutdown Current | <0.5µA - ensures near-zero system leakage during deep sleep, essential for wearable and IoT endpoint longevity. |
Pinout & Package
TPS610993YFFT is housed in a 6-ball, 1.23mm × 0.88mm DSBGA (WCSP) package with bottom-side solder balls. This ultra-compact, low-profile package enables direct integration into space-limited wearable PCBs and flexible substrates.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | Power input | Accepts 0.7V–5.5V source; connects to battery or primary rail; UVLO activates below 0.7V. |
| SW | Switch node | Drives external 2.2µH inductor; carries pulsed high-side current; requires low-ESR ceramic capacitor at VOUT. |
| EN | Enable control | Logic-high (>1.2V) enables operation; logic-low (<0.4V) forces true shutdown with full input-output isolation. |
| GND | Power ground | Primary return path for switch current and IC bias; must be low-impedance connection to thermal pad. |
| VOUT | Regulated output | Delivers fixed 3.0V ±2%; supplies load directly; decoupled with ≥10µF ceramic capacitor. |
| FB | Feedback reference | Internally shorted to GND for fixed 3.0V output - no external resistors required; unused in this variant. |
Key Features
| Feature | Design Value |
|---|---|
| Hysteretic current-mode control | Enables zero-external-compensation design, eliminates loop stability concerns, and maintains regulation down to 10µA load without burst-mode noise. |
| Down mode regulation | Maintains stable 3.0V output even when input exceeds 3.0V (up to VOUT + 0.5V), avoiding need for separate LDO in hybrid supply architectures. |
| True shutdown disconnect | Breaks conductive path between VIN and VOUT using integrated PMOS rectifier, reducing system standby current to sub-µA levels. |
| Integrated OVP and thermal protection | 5.8V output overvoltage clamp and 150°C junction thermal shutdown prevent damage during fault conditions without external circuitry. |
| Ultra-low IQ architecture | Separate 400nA (VIN) and 600nA (VOUT) quiescent paths minimize total system leakage - critical for multi-year battery life in wearables. |

FAQ
What is the exact output voltage tolerance of the TPS610993YFFT?
The TPS610993YFFT delivers a fixed 3.0V output with ±2% accuracy over temperature (–40°C to 125°C) and line/load conditions, as verified in Section 6.5 of the official datasheet. This tight tolerance eliminates need for post-regulation and ensures reliable operation of 3.0V-tolerant MCUs and sensors without additional voltage trimming.
Does the TPS610993YFFT require external feedback resistors?
No - the TPS610993YFFT is a fixed-output variant with internal feedback tied to GND, so the FB pin is not used and no external resistors are required. This simplifies layout, reduces BOM cost, and improves reliability compared to adjustable versions like TPS61099YFFT.
How does the TPS610993YFFT behave when input voltage exceeds 3.0V?
When VIN rises above 3.0V, the TPS610993YFFT automatically enters down mode (regulating VOUT at 3.0V) until VIN reaches VOUT + 0.5V (3.5V), then transitions to pass-through mode where VOUT ≈ VIN – (IL × RDS(on)_HS). This avoids unnecessary switching losses and extends battery life in partial-charge states.
What is the maximum continuous output current supported by the TPS610993YFFT?
The TPS610993YFFT supports up to ~300mA continuous output current when stepping up from 3.3V to 3.0V (pass-through) or boosting from lower inputs, constrained by thermal limits and the 0.8A minimum peak switch current limit. At 200mA load, it achieves up to 93% efficiency per datasheet Figure 6-5.
Is the TPS610993YFFT compatible with coin-cell batteries?
Yes - the TPS610993YFFT operates from as low as 0.7V input, making it fully compatible with single-cell coin cells (e.g., CR2032, nominal 3.0V, discharge down to 2.0V) and alkaline cells (down to 0.7V). Its 400nA VIN quiescent current preserves capacity during extended standby periods typical in coin-cell applications.
