Product details
Overview
TPS610995DRVT from Texas Instruments is a synchronous boost converter optimized for ultra-low-power battery systems, delivering 3.6V fixed output voltage with 3.53–3.67V 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 TPS610995DRVT datasheet, TPS610995DRVT pinout, TPS610995DRVT application, or TPS610995DRVT equivalent, key selection criteria include its 3.6V fixed output tolerance, 0.8A peak switch current limit, hysteretic control topology, WCSP package footprint, and verified performance at 10µA–300mA loads across alkaline, Li-Mn, and coin-cell sources.
Technical Context
The TPS610995DRVT implements a hysteretic current-mode control architecture that dynamically adjusts switching frequency based on VIN, VOUT, and inductor value-enabling high efficiency without external compensation. Its dual-mode operation (boost/down/pass-through) is governed by precise thresholds: down mode activates when VIN > VOUT – 50mV, and pass-through engages at VIN > VOUT + 0.5V.
True shutdown disconnects load from input via full PMOS gate control, limiting shutdown current to ≤1.6µA into VIN. Internal feedback reference is fixed at 1.00V ±2%, with overvoltage protection triggering at 5.8V and thermal shutdown at 150°C with 25°C hysteresis-ensuring robustness in wearable and portable environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.6V (3.53–3.67V accuracy in PWM mode), eliminating external resistor divider |
| Quiescent Current (VOUT) | 600nA typical into VOUT pin-enables >1-year runtime on CR2032 at 10µA load |
| Input Voltage Range | 0.7V to 5.5V-supports single-cell alkaline, NiMH, Li-Mn, and Li-ion batteries from depletion to full charge |
| Peak Switch Current Limit | 0.8A minimum-supports ≥300mA output at 3.3V→5V conversion with 93% efficiency |
| Control Topology | Hysteretic current-mode-no compensation required, self-adapting frequency, burst mode below 100µA |
| Shutdown Disconnection | True load isolation-input-to-output leakage <0.5µA during disable, critical for zero-power standby |
| Overvoltage Protection | 5.8V threshold with 100–200mV hysteresis-prevents damage from misconfigured feedback networks |
Pinout & Package
TPS610995DRVT uses the DRV (WSON-6) package: 2mm × 2mm body, 6-pin exposed-pad layout with GND-connected PowerPad™ for thermal dissipation. Pin pitch is 0.5mm; recommended PCB pad layout per TI SLVSD88M.
| 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; requires low-ESR ceramic capacitor and careful routing to minimize EMI |
| EN | Enable logic input | Active-high (VIH ≥1.2V); must be pulled high or low-floating prohibited; enables true shutdown |
| GND | Power ground | Primary return path; ties to PowerPad™ for thermal and electrical integrity |
| VOUT | Regulated output | Delivers fixed 3.6V; connects to load and 10µF output capacitor; no FB connection needed |
| FB | Feedback input | Internally tied to GND for fixed-output versions-must not be left floating or externally connected |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low IQ into VOUT | 600nA ensures >10-year shelf life on coin cells when powering always-on sensors |
| Down mode regulation | Maintains stable 3.6V output even when VIN rises above 3.6V (e.g., fresh Li-ion at 4.2V) |
| Pass-through operation | Eliminates switching loss when VIN > VOUT + 0.5V-reducing heat and extending battery life |
| True shutdown isolation | Breaks input-to-output path completely-critical for medical wearables requiring zero standby drain |
| Burst mode at light load | Reduces switching cycles below 100µA, cutting dynamic losses while preserving 75% efficiency at 10µA |

Equivalent & Alternatives
The following parts are listed as comparable options for similar boost converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS610994DRVT | Fixed 3.3V output (3.23–3.37V), identical package and IQ specs | Suitable where system logic or RF ICs require 3.3V instead of 3.6V | Select when target rail matches 3.3V; same PCB layout but verify load regulation margin at 3.3V |
| TPS610996DRVT | Fixed 4.5V output (4.4–4.6V), same thermal and efficiency profile | Used in higher-voltage analog front-ends or legacy LCD drivers needing 4.5V bias | Choose for 4.5V systems; ensure input can sustain ≥4.5V under load given 0.8A limit |

FAQ
What is the output voltage tolerance of the TPS610995DRVT?
The TPS610995DRVT delivers a fixed 3.6V output with ±2% accuracy in PWM mode (3.53–3.67V), verified across –40°C to 125°C junction temperature and 0.7–5.5V input range. This tolerance is maintained in both boost and down modes, ensuring stable bias for precision analog circuits without external trimming.
Does the TPS610995DRVT require external feedback resistors?
No, the TPS610995DRVT does not require external feedback resistors. As a fixed-output variant, its 3.6V regulation is implemented internally; the FB pin is internally connected to GND. Connecting external components to FB may disrupt regulation and is explicitly prohibited per TI SLVSD88M.
How does the TPS610995DRVT behave when input voltage exceeds 3.6V?
When VIN rises above 3.6V, the TPS610995DRVT automatically enters down mode to maintain regulated 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-ensuring seamless operation across battery discharge curves.
What is the maximum continuous output current supported by the TPS610995DRVT?
The TPS610995DRVT supports up to 300mA continuous output current when converting from 3.3V to 3.6V, achieving up to 93% efficiency at 200mA. Peak switch current is limited to 0.8A minimum, allowing short-duration pulses beyond 300mA if thermally managed within the WSON-6 package's 71.7°C/W RθJA.
Can the TPS610995DRVT operate from a 0.7V input source?
Yes, the TPS610995DRVT operates from as low as 0.7V input-enabling use with deeply discharged alkaline or NiMH cells. Startup succeeds with >3kΩ load; heavier loads require VIN >1.5V for reliable soft-start completion, per TI characterization in SLVSD88M Section 7.3.4.
