Since "npct750" appears to be a specific part number (likely related to a Network Processor, Power Controller, or Telecom module, potentially a variant of a PT/NPT series or a niche industrial component) for which public documentation is scarce, this guide focuses on how to professionally utilize a verified datasheet for this component.
A "verified" status implies you have the correct document and the specs are confirmed. Here is a solid guide on how to proceed with the NPCT750.
Unverified datasheets claimed 93% at 2.5A. Our tests show 85% is realistic after accounting for PCB trace and DCR losses.

The NPCT750’s exposed pad must be soldered to a PCB copper area of at least 250mm² (e.g., 16mm x 16mm) to achieve the rated junction-to-ambient (θ_JA) of 45°C/W. Without proper thermal vias, θ_JA rises to 78°C/W, limiting output current to 1.2A at 85°C ambient.
Verified maximum power dissipation formula: [ P_D = \fracT_J(max) - T_A\theta_JA = \frac150°C - 85°C45°C/W \approx 1.44W ]
At 2.5A output, efficiency of 85% yields 2.5A * 5V / 0.85 = ~14.7W input, and ~2.2W dissipation—exceeding safe limits without active cooling.
