Product details
Overview
TPS61230ARNSR from Texas Instruments is a fully integrated synchronous step-up DC-DC converter optimized for single-cell Li-ion/Li-polymer battery-powered systems. It delivers up to 2.4 A at 5 V output from 2.5–4.5 V input, features dual 18-mΩ/21-mΩ MOSFETs, 1.15-MHz quasi-constant-frequency PWM operation, and true load disconnect during shutdown - enabling compact, high-efficiency power banks and USB power supplies.
For engineers reviewing the TPS61230ARNSR datasheet, TPS61230ARNSR pinout, TPS61230ARNSR application, or TPS61230ARNSR equivalent, key selection criteria include valley current limit (6 A), PFM/PWM mode transition behavior, thermal shutdown threshold (160 °C), soft-start time (1.05 ms), and VQFN-7 package compatibility with space-constrained portable designs.
Technical Context
The TPS61230ARNSR employs valley-current-mode control with quasi-constant on-time architecture, delivering stable regulation across 2.5–4.5 V input while maintaining 1.15 MHz nominal switching frequency under medium-to-heavy loads. Its internal 18-mΩ high-side and 21-mΩ low-side MOSFETs enable up to 96% peak efficiency and support continuous 2.4-A output at 5 V with minimal external components.
At light loads, it automatically transitions to pulse-frequency modulation (PFM) to reduce quiescent current to 20 µA (typical), extending battery life. Integrated protections include output overvoltage (5.8 V threshold), hiccup-mode short-circuit response, thermal shutdown (160 °C), and true load disconnect - ensuring robust operation in consumer and industrial portable applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.5 V to 4.5 V - supports full discharge range of single-cell Li-ion batteries without UVLO dropout. |
| Output Voltage Range | Adjustable 2.5 V to 5.5 V via external resistor divider - enables flexible system rail generation including standard 5-V USB compliance. |
| Switching Frequency | 1.15 MHz (typical, PWM mode) - permits use of sub-2-mm-height 1-µH inductors and small ceramic capacitors for ultra-compact layouts. |
| Valley Current Limit | 6 A (typical) - defines maximum sustainable output current before entering current-limit protection; enables 12-W peak power delivery. |
| Quiescent Current | 20 µA (typical, VIN = 4.2 V, no load) - minimizes standby power loss in battery-backed systems requiring long shelf life. |
| Soft Start Time | 1.05 ms (typical) - controls inrush current during power-up to prevent input voltage sag and ensure reliable startup into capacitive loads. |
| Thermal Shutdown | 160 °C (typical, rising) with 10 °C hysteresis - protects IC and PCB from thermal runaway during sustained overload or poor heatsinking. |
Pinout & Package
TPS61230ARNSR is housed in a 2.0-mm × 2.0-mm × 0.9-mm VQFN-7 package (RNS suffix) with wettable flanks, optimized for automated optical inspection and thermal performance in dense portable PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CBST (Pin 1) | Bootstrap supply | Connects external 10-nF capacitor between SW and CBST to generate gate drive voltage for high-side MOSFET; critical for proper switching. |
| EN (Pin 2) | Enable control | Logic-level input: >1.2 V enables operation; <0.4 V forces shutdown with <1 µA input current and true load disconnect. |
| FB (Pin 3) | Feedback sensing | Monitors output voltage via external resistor divider; regulates to 1.195 V (typical) reference - sets VOUT = 1.195 × (1 + R1/R2). |
| VIN (Pin 4) | Main input supply | Accepts 2.5–4.5 V battery or adapter input; powers internal circuitry and low-side FET source; requires local 10-µF ceramic decoupling. |
| SW (Pin 5) | Switch node | Drain of low-side FET and source of high-side FET; carries high di/dt switching current - must be routed with minimal loop area and adjacent to GND plane. |
| GND (Pin 6) | Analog/digital ground | Common return for internal reference, error amplifier, and low-side FET source; requires low-impedance connection to power ground plane. |
| VOUT (Pin 7) | Regulated output | Delivers boosted output (up to 5.5 V); connects to output capacitor bank (e.g., 2×22 µF) and load; provides feedback path via FB pin. |
Key Features
| Feature | Design Value |
|---|---|
| True load disconnect | Shuts off both internal FETs during EN = low, isolating VOUT from VIN - prevents battery drain in standby mode. |
| Integrated dual MOSFETs | 18-mΩ high-side + 21-mΩ low-side RDS(on) - eliminates external switch losses and reduces BOM count for 5-V/2.4-A boost solutions. |
| PFM/PWM auto-transition | Seamlessly shifts from 1.15-MHz PWM (medium/heavy load) to variable-frequency PFM (light load) - maintains >85% efficiency down to 100 µA output current. |
| Output overvoltage protection | Triggers at 5.8 V (typical) - disables switching and holds output safe during feedback divider fault or transient overregulation. |
| Hiccup-mode short-circuit protection | Enters 23-ms off / 3.5-ms on cycling when output shorts - limits average power dissipation and enables self-recovery after fault removal. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar boost converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS61236RNSR | Fixed 5-V output (no FB divider required); identical 2.0×2.0-mm VQFN-7 package and 6-A current limit. | Eliminates two external resistors but lacks output voltage flexibility - suitable only where 5 V is mandatory. | Select TPS61236RNSR when board space is constrained and output voltage is fixed; retain TPS61230ARNSR for adjustable or multi-rail designs. |
| RT9086AGQW | 2.7–5.5 V input; 5-V fixed output; 3.5-A current limit; 2.5-mm × 2.5-mm DFN-10 package; no true load disconnect. | Lower current capability and larger footprint; lacks shutdown isolation - may require external load switch for battery preservation. | Choose RT9086AGQW only if lower cost outweighs reduced current headroom and missing load disconnect functionality. |
Compared with TPS61230ARNSR, TPS61236RNSR offers identical performance in a pin-compatible form with simplified design, while RT9086AGQW trades current capacity, package size, and protection features for cost - making TPS61230ARNSR optimal for flexible, high-reliability 5-V boost applications demanding true load isolation.

FAQ
What is the maximum continuous output current of the TPS61230ARNSR?
The TPS61230ARNSR supports up to 2.4 A continuous output current at 5 V with 3.6-V input, limited by its 6-A valley current sense threshold and thermal design. Actual achievable current depends on PCB layout, ambient temperature, and input/output voltage differential - derate linearly above 85 °C junction temperature per TI's thermal metrics.
Does the TPS61230ARNSR support output voltages higher than 5 V?
Yes, the TPS61230ARNSR supports adjustable output voltages from 2.5 V to 5.5 V using an external resistor divider on the FB pin. The internal reference is 1.195 V (typical), so setting R1/R2 ratio accordingly allows precise configuration - e.g., 5.4 V output is achievable and within absolute maximum ratings.
How does the TPS61230ARNSR handle short-circuit conditions on the output?
When the TPS61230ARNSR detects an output short, it enters hiccup-mode protection: disabling switching for 23 ms (THC_OFF), then attempting restart for 3.5 ms (THC_ON). This cycle repeats until the short is removed, limiting average power dissipation and preventing thermal damage while enabling automatic recovery.
Can the TPS61230ARNSR operate with input voltage below 2.5 V?
No - the TPS61230ARNSR has a 2.5-V input UVLO threshold (rising) and will not start or sustain regulation below that level. Input voltage must remain ≥2.5 V for normal operation; operation below this risks unregulated output or device latch-up per absolute maximum ratings.
Is the TPS61230ARNSR pin-compatible with other devices in the TPS6123x family?
The TPS61230ARNSR shares the same 2.0-mm × 2.0-mm VQFN-7 (RNS) package and pinout with TPS61236RNSR and TPS61232RNSR, enabling direct PCB reuse for fixed-output variants. However, FB pin usage differs: TPS61230ARNSR requires external divider, while fixed-output versions tie FB to VOUT.
