30 Amp, No Heatsink, Isolated DC/DC Converter
The PQ48053HTA30 PowerQor™ Tera converter is a next-generation, board-mountable, isolated,fixed switching frequency DC/DC converter that uses synchronous rectification to achieve extremely high conversion efficiency. The power dissipated by the converter is so low that a heatsink is not required, which saves cost, weight, height, and application effort. The Tera series converters offer the maximum useable output current for any standard “half-brick” module.
PQ48053HTA30 Module
Operational Features
• Ultra-high efficiency, 92% at full rated load current • Delivers up to 30 amps of output current with minimal derating - no heatsink required • Wide input voltage range: 39V – 75V • Fixed frequency switching provides predictable EMI performance
Protection Features
• Input under-voltage lockout and over-voltage shutdown protects against abnormal input voltages • Output current limit and short circuit protection • Output over-voltage protection • Thermal shutdown
Mechanical Features
• Industry standard pin-out configuration • Industry standard size: 2.3” x 2.4” • Total height only 0.44”, permits better airflow and smaller card pitch • Total weight: 2.6 oz. (75 grams)
Control Features
• On/Off control referenced to input side (negative logic) • Remote sense for the output voltage compensates for output distribution drops • Output voltage trim permits custom voltages and voltage margining
Safety Features
• 2000V, 10 MΩ input-to-output isolation • UL/cUL 60950 recognized (US & Canada), basic insulation rating • TUV certified to EN60950 • Meets 72/23/EEC and 93/68/EEC directives • Meets UL94V-0 flammability requirements

Recommended pin length is 0.03” (0.76mm) greater than the PCB thickness. 5) All Pins: Material - Copper Alloy Finish - Tin/Lead over Nickel plate 6) Undimensioned components are shown for visual reference only. 7) All dimensions in inches (mm) Tolerances: x.xx +/-0.02 in. (x.x +/-0.5mm) x.xxx +/-0.010 in. (x.xx +/-0.25mm) 8) Weight: 2.6 oz. (75g) typical 9) Workmanship: Meets or exceeds IPC-A-610C Class II 10) UL/TUV standards require a clearance greater than 0.04”
(1.02mm) between input and output for Basic insulation. This issue should be considered if any copper traces are on the top side of the user’s board. Note that the ferrite cores are considered part of the input/primary ciruit.
