Key Features

  • Integrated inductor, MOSFETs, and PWM controller in a 30-pad VQFN-like module reduces external component count to as few as 4 parts, cutting design time and PCB area by up to 50% versus discrete buck designs
  • Wide 3 V to 36 V input range with 3 A continuous output covers industrial 24 V bus, telecom 48 V-derived rails, and automotive 12 V systems in a single-footprint solution
  • Current-mode PWM control with adjustable output from 1 V to 16 V enables precise supply rails for FPGAs, DSPs, and multi-rail industrial processors with minimal external passives

Applications

The TPSM63603SRDHR is designed for industrial automation, factory robotics, and distributed power systems where engineers need a complete step-down power supply in a compact, pre-certified module. It simplifies compliance by integrating magnetics and power stage into a single package, reducing EMI variability caused by discrete component placement. The module also suits telecom line cards and embedded computing platforms requiring a reliable 3 A supply rail from a 24 V or 48 V input bus with minimal engineering effort.

Frequently Asked Questions

What input and output voltage ranges does the TPSM63603SRDHR support, and what output current can it deliver continuously?

The TPSM63603SRDHR accepts input voltages from 3 V to 36 V with a 24 V nominal and produces an adjustable output from 1 V to 16 V at up to 3 A continuous current. This wide input range covers standard 12 V, 24 V, and 28 V industrial buses, while the adjustable output accommodates nearly any logic or memory supply rail typically found in embedded processing systems.

How does integrating the inductor into the TPSM63603SRDHR module benefit PCB layout in an industrial PLC design?

With the inductor integrated into the 30-pad module package, the TPSM63603SRDHR eliminates the largest and most placement-sensitive discrete component in a buck converter design. This reduces the switching power stage footprint by approximately 50% compared to a discrete implementation and removes the need to route high-current switching loops across the PCB, cutting radiated EMI and simplifying layout for IEC 61000 compliance in PLC and industrial controller designs.

What control technique does the TPSM63603SRDHR use, and how does current-mode PWM improve transient response for FPGA core rails?

The TPSM63603SRDHR uses current-mode pulse width modulation (PWM) control, which provides inherent cycle-by-cycle current limiting and faster transient response compared to voltage-mode control. For FPGA core rails that demand tight voltage regulation during sudden load steps of 1 A to 2 A, current-mode control typically recovers the output voltage within 10 µs to 30 µs, protecting the FPGA core from under-voltage faults during wake-up or computation-intensive tasks.

What package does the TPSM63603SRDHR use, and which external components are still required to complete the power supply design?

The TPSM63603SRDHR comes in a 30-pad LGA-style power module package measuring approximately 6.5 mm x 5.0 mm. Despite the high integration, the designer still needs to add an input bypass capacitor (typically 10 µF to 47 µF ceramic), an output capacitor (22 µF to 100 µF), an output voltage setting resistor divider (2 resistors), and optionally a soft-start capacitor. This results in as few as 4 to 6 external components for a complete 3 A regulated supply.
