Key Features
- Wide 3 V to 36 V input range with 24 V nominal operation covers 12 V, 24 V, and 28 V industrial and automotive bus voltages in a single module
- Integrated current-mode PWM controller and power stage in a 30-pin QFN module eliminates external inductors and simplifies PCB layout
- Pb-free and RoHS-compliant RDHR package with YTEOL 15-year lifecycle rating supports long-service industrial and automotive designs
Applications
TPSM63603RDHR is deployed in industrial automation equipment, factory PLCs, and motor drive auxiliary supplies where a 24 V bus must be stepped down to 3.3 V, 5 V, or 12 V rails using a compact module without external magnetic components. Its 3 V to 36 V input range also covers 28 V avionics and automotive 24 V truck bus applications where board space is limited. The integrated power module approach accelerates time to certification in safety-rated systems by reducing the number of discrete components requiring individual qualification.

Frequently Asked Questions
What is the input voltage range of TPSM63603RDHR and which industrial bus voltages does it support?
TPSM63603RDHR accepts input voltages from 3 V to 36 V with a nominal design point at 24 V, covering 12 V automotive, 24 V industrial, and 28 V avionics bus standards in a single module. This wide range eliminates the need for separate regulator designs for each bus voltage, reducing BOM complexity in multi-rail industrial control systems.
How does the integrated power module approach of TPSM63603RDHR reduce PCB design effort versus a discrete buck converter at 24 V input?
TPSM63603RDHR integrates the PWM controller, power switches, and passive components into a single 30-pin QFN module, eliminating the need to select and place external inductors, bootstrap capacitors, and gate drive resistors individually. A discrete 24 V to 5 V buck converter typically requires 10 to 15 external components; the module approach reduces external passives to input and output filter capacitors, cutting layout iterations and reducing total circuit footprint to under 2 cm².
For a 24 V industrial PLC power supply, what control mode does TPSM63603RDHR use and what stability advantage does it provide?
TPSM63603RDHR uses current-mode pulse width modulation control, which provides inherent cycle-by-cycle current limiting and faster transient response compared to voltage-mode control. In a 24 V PLC application where load steps of 0.5 A to 3 A occur during actuator switching, current-mode operation typically reduces output voltage deviation by 30% to 50% versus voltage-mode at equivalent output capacitance, improving regulation to within ±2% under dynamic conditions.
What is the lifecycle rating of TPSM63603RDHR and how does it support long-service industrial equipment procurement?
TPSM63603RDHR carries a YTEOL (years to end of life) rating of 15 years, indicating Texas Instruments plans to manufacture and supply this device for at least 15 years from the product release date. This extended lifecycle commitment directly supports industrial equipment manufacturers whose systems have 10 to 20 year field service requirements, reducing the risk of mid-lifecycle component obsolescence and costly redesign cycles for certified machinery.
