Product details
Overview
TPS610995DRVR from Texas Instruments is a synchronous boost converter optimized for ultra-low-power battery systems, delivering fixed 3.6V output with 3.53–3.67V accuracy, 0.7–5.5V input range, and 1µA quiescent current. 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 TPS610995DRVR datasheet, TPS610995DRVR pinout, TPS610995DRVR application, or TPS610995DRVR equivalent, key selection criteria include fixed-output voltage tolerance, hysteretic control efficiency at µA loads, WCSP/WSON package thermal performance, and verified down-mode behavior when VIN exceeds VOUT.
Technical Context
The TPS610995DRVR implements a hysteretic current-mode control topology that dynamically adjusts switching frequency based on input voltage, output load, and inductor value-enabling >75% efficiency at 10µA load and up to 93% at 200mA. It operates across three functional 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 (0.8–1.25A), output overvoltage protection (5.6–6.0V), undervoltage lockout (0.6–0.7V rising), and thermal shutdown (150°C trip, 125°C hysteresis). The device consumes only 400nA into VIN and 600nA into VOUT under light-load conditions, with shutdown current below 0.5µA.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.6V ±0.07V (3.53–3.67V) - ensures stable bias for precision analog sensors without external feedback resistors. |
| Input Voltage Range | 0.7V to 5.5V - supports single-cell alkaline, NiMH, Li-Mn, and rechargeable Li-ion batteries across full discharge curve. |
| Quiescent Current | 400nA into VIN / 600nA into VOUT - minimizes standby power loss in always-on wearable subsystems. |
| Peak Switch Current Limit | 0.8A minimum - sustains regulated output during transient loads up to 300mA in boost mode. |
| Efficiency | 75% at 10µA load (fixed-VOUT); 93% at 200mA - enables multi-year operation from coin cells in low-duty-cycle applications. |
| Down Mode Regulation | Active when VIN > VOUT - maintains 3.6V output even as battery voltage rises above target, eliminating need for external LDO. |
| Shutdown Disconnection | True load isolation - reduces system leakage to <0.5µA, critical for zero-power sleep states in medical wearables. |
Pinout & Package
TPS610995DRVR is packaged in a 6-pin 2mm × 2mm WSON (DRV) package with exposed thermal pad. Pin functions are validated per TI SLVSD88M Rev. AUGUST 2026.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | Power input | Accepts 0.7–5.5V supply; connects to input capacitor and battery anode; UVLO triggers at 0.6V. |
| SW | Switch node | Drives external 2.2µH inductor; carries peak currents up to 1.25A; requires low-ESR ceramic output cap. |
| EN | Enable logic input | Active-high control: VIH ≥ 1.2V (VIN > 1.5V); VIL ≤ 0.4V; leakage <50nA; must not float. |
| GND | Power ground | Reference for all signals; connects to thermal pad and PCB ground plane for RθJB = 33.9°C/W. |
| VOUT | Regulated output | Delivers fixed 3.6V; supplies load directly; supports down mode and pass-through operation. |
| FB | Feedback reference | Internally tied to GND for fixed-output versions; unused and must be grounded per datasheet. |
Key Features
| Feature | Design Value |
|---|---|
| Hysteretic current-mode control | Eliminates external compensation; adapts switching frequency to load/inductor/VIN to maximize light-load efficiency. |
| Down mode regulation | Maintains 3.6V output when VIN exceeds VOUT (up to VIN = VOUT + 0.5V), avoiding cascaded regulation losses. |
| True shutdown disconnection | Breaks VIN-to-VOUT path via PMOS gate control, reducing system standby current to sub-µA levels. |
| Integrated OVP & thermal protection | 5.6–6.0V output overvoltage cutoff and 150°C junction shutdown prevent damage during fault conditions. |
| Ultra-low IQ architecture | Sub-1µA total quiescent current enables >10-year shelf life in battery-backed memory LCDs and sensor nodes. |

FAQ
What is the output voltage tolerance of the TPS610995DRVR?
The TPS610995DRVR delivers a fixed 3.6V output with a guaranteed tolerance of ±0.07V (3.53V to 3.67V) under PWM mode operation across –40°C to 125°C junction temperature. This specification is confirmed in Section 6.5 of the SLVSD88M datasheet and applies to all production units in the DRV (WSON) package. The TPS610995DRVR achieves this accuracy without external feedback components due to factory-trimmed internal reference and EEPROM programming.
Does the TPS610995DRVR support down mode operation, and how does it behave?
Yes, the TPS610995DRVR supports down mode regulation when input voltage exceeds the 3.6V output target but remains below VOUT + 0.5V (i.e., VIN < 4.1V). In this mode, the device actively regulates VOUT at 3.6V by controlling the rectifying PMOS gate voltage, resulting in a variable voltage drop across the switch. The TPS610995DRVR automatically transitions to pass-through mode when VIN reaches or exceeds 4.1V, allowing VOUT to track VIN minus conduction losses. This behavior is fully documented in Section 7.3.8 of the datasheet.
What package options are available for the TPS610995DRVR, and which one is used in this part number?
The TPS610995DRVR uses the 6-pin 2mm × 2mm WSON package (orderable code "DRV"), as indicated by the suffix "DRVR" in the full part number. While the TPS61099x family also offers a 6-ball 1.23mm × 0.88mm WCSP (YFF) variant, the DRVR designation confirms the WSON package with exposed thermal pad. This package provides RθJB = 33.9°C/W and is optimized for reflow-compatible PCB assembly in space-constrained wearables.
How does the TPS610995DRVR achieve ultra-low quiescent current, and what are the measured values?
The TPS610995DRVR achieves ultra-low quiescent current through a combination of optimized bias circuitry and hysteretic control architecture. It draws just 400nA into the VIN pin and 600nA into the VOUT pin under no-load, enabled conditions-verified across –40°C to 85°C in Section 6.5 of the datasheet. These values represent total operating current, including internal reference, error amplifier, and gate drivers, enabling multi-year operation from CR2032 coin cells in always-on applications.
Is the FB pin required to be connected for the TPS610995DRVR, and if so, how?
No, the FB pin is not required for external connection on the TPS610995DRVR because it is a fixed-output version. Per Section 5 and Figure 5-2 of the datasheet, the FB pin must be connected directly to GND to disable the adjustable feedback path and activate the internal 3.6V reference. Leaving FB floating or connecting it to any other node will cause undefined regulation behavior or failure to start. This grounding requirement is mandatory for proper operation of the TPS610995DRVR.
