Typical Applications
TPS61230 is suitable for 6 applications: Battery-Powered Portable Devices, USB Power Supply, LED Driver, Industrial Sensor Nodes, Portable Audio Equipment, Medical Monitoring Devices.
Battery-Powered Portable Devices
The TPS61230 boosts a single Li-Ion cell (2.5-4.2 V) to a regulated 5-V rail for powering microcontrollers, sensors, and displays. Its high efficiency (up to 96%) and low quiescent current (20 µA) extend battery life. The 5-A switch supports peak loads, and the small VQFN-10 package fits compact designs. Power-save mode ensures efficiency at light loads, making it ideal for wearables and IoT devices.
Recommended
USB Power Supply
The TPS61230 can generate a 5-V USB supply from a 2.5-3.3-V input, enabling USB-powered devices from battery sources. It delivers up to 2.4 A at 5 V, sufficient for charging or powering USB peripherals. The integrated synchronous rectifier eliminates external diodes, and the 1.5-MHz switching frequency allows small inductors. Overcurrent protection ensures safe operation.
Recommended
LED Driver
The TPS61230 can drive high-brightness LEDs from a low-voltage battery by boosting to the required forward voltage. Its adjustable output allows precise current control via a series resistor. The high efficiency reduces heat dissipation, and the 5-A switch supports multiple LEDs in series. Power-save mode maintains efficiency at low brightness levels.
Recommended
Industrial Sensor Nodes
In industrial IoT, the TPS61230 boosts a 3.3-V rail to 5 V for sensors and wireless transceivers. Its wide input range and high efficiency are critical for energy harvesting systems. The device's small footprint and thermal performance suit enclosed sensor nodes. The 20-µA quiescent current is ideal for battery-powered remote monitoring.
Recommended
Portable Audio Equipment
The TPS61230 provides a clean 5-V rail for audio codecs and amplifiers from a single Li-Ion cell. Its 1.5-MHz switching frequency keeps noise above the audio band, and the low output ripple ensures high audio quality. The high efficiency extends playback time, and the small package fits portable audio players.
Recommended
Medical Monitoring Devices
The TPS61230 is suitable for portable medical devices that require a regulated 5-V supply from a small battery. Its high efficiency and low quiescent current are crucial for long battery life in continuous monitoring. The device's reliability and protection features (overcurrent, thermal shutdown) ensure safe operation in medical applications.

Key Differentiators
- Higher switch current limit (5 A) than TPS61030 (4 A) (vs TPS61030)
- Smaller package (VQFN-10) vs TPS61030 (TSSOP-16) (vs TPS61030)
- Adjustable output vs fixed 5-V on TPS61232 (vs TPS61232)
Design Notes
For optimal performance, place the input and output capacitors as close as possible to the VIN and VOUT pins. Use a 10-µF ceramic capacitor on the input and a 22-µF ceramic capacitor on the output. The inductor should be placed near the SW pin with short, wide traces to minimize parasitic inductance and resistance.
The TPS61230's exposed thermal pad must be soldered to a large copper area on the PCB to dissipate heat effectively. At high output currents, the power dissipation can be significant. Ensure adequate thermal vias under the pad to conduct heat to other layers. The thermal resistance (θJA) is typically 40°C/W with proper layout.
Avoid using an inductor with saturation current below the peak switch current (5 A). Also, ensure the feedback resistor divider uses 1% tolerance resistors to maintain output voltage accuracy. Do not exceed the absolute maximum input voltage of 5.5 V, and provide a proper soft-start to prevent inrush current.
