Typical Applications
TPS54360DDAR is suitable for 6 applications: Industrial Power Supplies, Automotive Electronics, Telecom and Networking, Point-of-Load Converters, Battery-Powered Equipment, Test and Measurement.
Industrial Power Supplies
The TPS54360DDAR's 60V input range and 3.5A output make it ideal for industrial power supplies that need to step down from 24V or 48V buses. Its current mode control provides fast transient response, ensuring stable output for motors, sensors, and PLCs. The wide input range handles voltage spikes common in industrial environments, and the Eco-modeβ’ maintains efficiency at light loads, reducing standby power consumption.
Recommended
Automotive Electronics
In automotive systems, the TPS54360DDAR steps down 12V or 24V battery voltage to power infotainment, ADAS, and body control modules. Its 65V absolute maximum input rating withstands load dump transients, and the -40Β°C to 125Β°C temperature range suits under-hood environments. The enable pin allows sequencing with other rails, and the high switching frequency reduces external component size, saving PCB space in space-constrained designs.
Recommended
Telecom and Networking
The TPS54360DDAR is used in telecom and networking equipment to convert 48V backplane voltages to lower rails for FPGAs, ASICs, and line cards. Its 3.5A output can power multiple loads, and the adjustable frequency allows optimization for efficiency or size. The high-side MOSFET's low RDS(on) minimizes losses, and the current mode control ensures stable operation under varying load conditions, critical for reliable data transmission.
Recommended
Point-of-Load Converters
As a point-of-load (POL) converter, the TPS54360DDAR provides a regulated low-voltage rail close to the load, reducing distribution losses. Its 0.8V minimum output supports modern low-voltage digital cores, and the 3.5A current handles high-power processors. The small HSOIC package and high switching frequency allow a compact footprint, ideal for space-limited designs. The enable pin facilitates power sequencing in multi-rail systems.
Recommended
Battery-Powered Equipment
The TPS54360DDAR's Eco-modeβ’ pulse skipping maintains high efficiency at light loads, extending battery life in portable equipment. Its wide input range accommodates battery voltage variations, and the low quiescent current in shutdown mode (via enable pin) reduces standby power. The device can step down from multi-cell battery packs to power sensors, wireless modules, and microcontrollers, making it suitable for IoT devices and portable instruments.
Recommended
Test and Measurement
In test and measurement equipment, the TPS54360DDAR provides clean, stable power rails for precision analog circuits. Its current mode control ensures low output ripple, and the adjustable frequency allows synchronization to avoid interference with sensitive measurements. The wide input range supports various supply voltages, and the thermal performance of the PowerPAD package ensures reliable operation in benchtop instruments that run continuously.

Key Differentiators

- Adjustable switching frequency (vs TPS5450DDAR)
- Eco-modeβ’ for light load efficiency (vs LMR16030)
Design Notes
For optimal performance, place the input capacitor (10Β΅F) and output capacitor (47Β΅F) as close to the IC as possible. Use a solid ground plane and connect the PowerPAD to the ground plane with multiple vias to enhance thermal dissipation. Keep the SW node trace short and wide to minimize parasitic inductance and EMI.
The TPS54360DDAR can dissipate significant power at high input-output voltage differences. For example, at VIN=24V, VOUT=5V, and 3.5A load, power dissipation is approximately 66W (assuming 90% efficiency). The HSOIC PowerPAD package has a thermal resistance of about 40Β°C/W (theta_JA) with proper PCB copper. Ensure adequate copper area and airflow to keep junction temperature below 125Β°C.
Do not exceed the absolute maximum input voltage of 65V. Use a bootstrap capacitor (0.1Β΅F) between BOOT and SW pins. Set the switching frequency using an external resistor from RT/CLK to GND; avoid leaving RT/CLK floating. Ensure the feedback resistor divider uses 1% tolerance resistors to maintain output voltage accuracy.
Compliance Information
RoHS compliant per TI product page. Not AEC-Q100 qualified; choose TPS54360QDDARQ1 for automotive.
