What are the key features of TPS54362HPWP?
- Wide 3.6 V to 60 V input range supports 24 V and 48 V industrial bus rails without external voltage clamping
- Pulse-frequency modulation (PFM) control achieves ultra-low quiescent current for always-on light-load standby applications
- 1 A continuous output current with voltage-mode control enables stable regulation across a broad load range
What is TPS54362HPWP used for?
The TPS54362HPWP powers microcontrollers, sensors, and communication modules in industrial automation equipment and smart building controllers directly from 24 V or 48 V bus rails, eliminating intermediate bus conversion stages. Its ultra-low quiescent current from PFM control makes it ideal for always-on standby circuits in metering, building automation, and remote monitoring nodes where energy efficiency during light-load periods is critical. The 60 V input rating also accommodates automotive 48 V mild-hybrid systems and PoE-powered industrial edge devices.

Frequently Asked Questions
What input voltage range does TPS54362HPWP support, and which industrial bus standards does it cover?
The TPS54362HPWP accepts input voltages from 3.6 V to 60 V, covering 24 V industrial automation buses, 48 V telecom and mild-hybrid automotive rails, and nominal 12 V systems, making it a single-IC solution for powering low-current loads across multiple industrial voltage standards without an intermediate converter.
How does the PFM control mode of TPS54362HPWP benefit always-on standby circuits in industrial equipment?
The pulse-frequency modulation control of the TPS54362HPWP reduces switching frequency at light loads, dropping quiescent current to microamp levels during standby. This allows industrial sensors, wireless nodes, and building automation controllers to remain powered from a 48 V bus for extended periods without significant battery drain or system heating.
What is the maximum output current of TPS54362HPWP, and what types of loads can it power directly?
The TPS54362HPWP delivers up to 1 A of continuous output current, which is sufficient to directly power a 32-bit microcontroller, a Bluetooth or Zigbee radio module, multiple sensor ICs, and supporting logic circuitry from a single regulated output rail in compact industrial IoT nodes.
In a 48 V automotive mild-hybrid design, how does TPS54362HPWP provide a regulated 3.3 V or 5 V rail?
In a 48 V mild-hybrid system, the TPS54362HPWP steps down the 48 V bus to a regulated 3.3 V or 5 V output using its internal voltage-mode buck topology with an external resistor divider setting the output voltage. The 60 V rated input withstands load-dump transients up to 58 V, protecting the converter and downstream logic circuits during sudden load disconnection events.
