Product details
Overview
TPS61230ARNST from Texas Instruments is a high-efficiency 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, integrates dual 18-mΩ (HS) / 21-mΩ (LS) MOSFETs, operates at 1.15-MHz quasi-constant frequency, and supports true load disconnect in shutdown. It is used in USB power banks and portable audio amplifiers requiring compact, high-current boost capability.
For engineers reviewing the TPS61230ARNST datasheet, TPS61230ARNST pinout, TPS61230ARNST application, or TPS61230ARNST equivalent, key selection criteria include its 6-A valley current limit, 20-µA quiescent current in PFM mode, adjustable output voltage via external resistor divider, thermal shutdown at 160 °C, and 2.0-mm × 2.0-mm VQFN-7 package with integrated protection features.
Technical Context
The TPS61230ARNST uses valley-current-mode control with quasi-constant on-time architecture, enabling fast transient response and stable regulation across 2.5–4.5 V input and 2.5–5.5 V output ranges. Its internal dual-FET structure eliminates external switch requirements, while the CBST bootstrap capacitor enables high-side gate drive.
It dynamically switches between PWM (1.15 MHz, medium/heavy load) and PFM (variable frequency, light load) modes to maintain >90% efficiency from 10 mA to 2.4 A. Protection includes output overvoltage (5.7–5.99 V), hiccup-mode short-circuit response, UVLO (2.5 V rising threshold), and thermal shutdown with 10 °C hysteresis.
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 brownout. |
| Output Current Capability | Up to 2.4 A at 5 V - enables high-power USB peripheral charging and audio amplifier rails. |
| Switching Frequency | 1.15 MHz typical - allows use of ≤1-µH inductors and small ceramic capacitors for ultra-compact layouts. |
| Quiescent Current | 20 µA in PFM mode - extends battery runtime in standby or low-power system states. |
| Valley Current Limit | 4.8–7.8 A - provides robust overcurrent protection during startup and overload without latch-off. |
| Feedback Reference Voltage | 1.171–1.219 V - enables precise output voltage setting via external resistor divider with <±2% tolerance. |
| Thermal Shutdown Threshold | 160 °C - protects against sustained overload or poor PCB thermal design in sealed enclosures. |
Pinout & Package
TPS61230ARNST is housed in a 2.0-mm × 2.0-mm × 0.9-mm VQFN-7 package with wettable flank leads for automated optical inspection. The exposed thermal pad (Pin 6 GND) must be soldered to a PCB thermal plane for reliable 125 °C junction operation.
| 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. |
| EN (Pin 2) | Enable control | Logic-high (>1.2 V) enables regulation; logic-low (<0.4 V) disables IC and disconnects load from input. |
| FB (Pin 3) | Output voltage feedback | Senses divided output voltage; internal reference is 1.195 V typical - sets VOUT = 1.195 × (1 + R1/R2). |
| VIN (Pin 4) | Main input supply | Provides power to internal circuitry and low-side FET source; requires ≥10-µF local ceramic decoupling. |
| SW (Pin 5) | Power switching node | Connects to inductor and CBST capacitor; carries high di/dt ripple - must be routed with minimal loop area. |
| GND (Pin 6) | Power and signal ground | Common return for analog reference, low-side FET source, and thermal pad - requires solid copper pour under package. |
| VOUT (Pin 7) | Regulated output | Delivers boosted output; requires ≥44-µF total ceramic capacitance (e.g., 2×22 µF) placed near VOUT/GND pins. |
Key Features
| Feature | Design Value |
|---|---|
| True load disconnect | Shuts off both internal FETs during EN=low, reducing input leakage to <1 µA and preventing battery drain. |
| Integrated dual MOSFETs | 18-mΩ HS + 21-mΩ LS switches eliminate external power devices and reduce BOM count by 4+ components. |
| PFM/PWM auto-transition | Seamlessly shifts between high-efficiency PFM (light load) and fixed-frequency PWM (heavy load) without external control. |
| 1.05-ms soft start | Controls output ramp rate to prevent inrush current and stabilize downstream LDOs or USB enumeration circuits. |
| Hiccup-mode short protection | Enters 23-ms off / 3.5-ms on cycling during output short - limits average power dissipation and enables self-recovery. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar boost converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS61088RHLR | Higher 10-A valley current limit; 2.7–12-V input; larger 3.0-mm × 3.0-mm VQFN-16 package. | Targets higher-power applications (e.g., 5-V/5-A USB PD sink); less suitable for space-constrained 2.0-mm footprint designs. | Select TPS61088RHLR only if >2.4-A output or >4.5-V input capability is required; not pin-compatible. |
| MT3608EN | Lower 4-A current limit; no true load disconnect; 2.0-mm × 2.0-mm QFN-6 package; no OVP or thermal shutdown. | Lacks critical protections for safety-critical or battery-backed systems; requires external enable and feedback compensation. | Consider MT3608EN only for cost-sensitive, non-safety applications with external protection circuitry and layout margin for thermal management. |
Compared with TPS61230ARNST, TPS61088RHLR offers higher current and wider input range but increases board area and BOM complexity, while MT3608EN reduces cost but sacrifices reliability, protection, and integration - making TPS61230ARNST optimal for compact, protected 5-V/2.4-A battery-powered systems.

FAQ
What is the maximum continuous output current of the TPS61230ARNST?
The TPS61230ARNST delivers up to 2.4 A continuously at 5 V output when supplied from 2.5–4.5 V input, verified under thermal conditions meeting TJ ≤ 125 °C with proper PCB copper pour. Its 6-A valley current limit provides headroom for transient surges but continuous operation above 2.4 A requires derating based on ambient temperature and layout thermal performance.
Does the TPS61230ARNST support adjustable output voltage?
Yes, the TPS61230ARNST supports fully adjustable output voltage from 2.5 V to 5.5 V using an external resistor divider connected to the FB pin. With a typical feedback reference voltage of 1.195 V, the output is set by VOUT = 1.195 × (1 + R1/R2). Fixed-output variants exist (e.g., TPS61230xARNSR), but TPS61230ARNST itself is the adjustable version.
How does the TPS61230ARNST manage efficiency at light loads?
The TPS61230ARNST automatically enters pulse-frequency modulation (PFM) mode below ~100 mA load, reducing switching frequency and quiescent current to 20 µA. This maintains >85% efficiency at 10 mA and >90% at 100 mA - critical for battery longevity in standby or sensor-monitoring applications where TPS61230ARNST operates most of its duty cycle.
What protection features are integrated into the TPS61230ARNST?
The TPS61230ARNST integrates output overvoltage protection (5.7–5.99 V trip), thermal shutdown (160 °C with 10 °C hysteresis), hiccup-mode short-circuit protection, input UVLO (2.5 V rising), and true load disconnect in shutdown. These eliminate need for external protection ICs in most portable designs, simplifying BOM and improving system-level reliability.
Is the TPS61230ARNST pin-compatible with other TI boost converters?
No, the TPS61230ARNST uses a unique 7-pin VQFN layout (CBST, EN, FB, VIN, SW, GND, VOUT) and is not pin-compatible with other TI boost ICs like TPS61088 or TPS61222. Its CBST pin requirement and absence of COMP/SS pins differentiate its routing and external component needs - PCB layout must be designed specifically for TPS61230ARNST.
