Product Overview
The ETD44 is a ferrite-core high-frequency transformer platform intended for isolated power conversion in industrial automation, medical electronics, new-energy equipment, smart-grid systems, telecom and data-center power, smart IoT devices, security equipment, UPS systems, battery chargers, and other switched power-electronics applications.
The transformer is excited by a controlled high-frequency alternating or pulsed waveform generated by a switching converter. The DC-bus values in the matrix describe the source system and do not mean that unswitched DC can be applied directly to a transformer winding.
Key Features
  • ETD Core Power Conversion Platform for medium-power applications
  • High Frequency Energy Transfer with ferrite material support
  • Low Loss and Efficiency Oriented Design
  • Stable Electrical Performance with controlled manufacturing
  • Controlled Leakage and Capacitance parameters
  • Low Noise Development considerations
  • Thermal Management Support
  • EMI Oriented Winding Options
  • Insulation and Compliance Control
  • PCB Integration and Custom Pinout
Customization Parameters
Major customizable parameters include converter topology, minimum and maximum bus voltage, switched winding waveform, switching frequency, duty cycle, continuous and peak power, turns ratio, magnetizing inductance, magnetizing current, air gap, peak and RMS winding current, flux-density limit, saturation margin, leakage-inductance target, DCR, AC winding resistance, interwinding capacitance, ferrite material, winding conductor, winding sequence, electrostatic shield, insulation system, dielectric test level, creepage, clearance, pins, leads, terminals, mounting, impregnation, potting, thermal protection, temperature-rise limit, marking, packaging, compliance documentation, and production-test criteria.
Applications
  • Industrial automation systems and robotics
  • Servo drives, motor drives, and control equipment
  • Medical electronics (appropriately evaluated)
  • Solar inverters and renewable-energy power modules
  • Energy-storage and battery-interface converters
  • Telecom rectifiers and communications power systems
  • Data-center server and AI power modules
  • Smart IoT gateways and industrial communication nodes
  • Security cameras and access control equipment
  • Emergency-power and UPS converters
  • EV charging equipment and auxiliary converters
  • Industrial battery chargers and formation equipment
Quality Control
Comprehensive quality control includes incoming material inspection, design review, in-process control, electrical testing, mechanical inspection, sample validation, and traceability systems. Testing may include magnetizing inductance, leakage inductance, turns ratio, polarity, DCR, dielectric strength, insulation resistance, capacitance, and thermal validation.
Why Choose Chipsen
  • Application Specific Customization
  • Custom Design Support
  • Broad Industrial Application Support
  • Drawing and Sample Based Development
  • Engineering Collaboration
  • Certification and Material Documentation
  • Flexible Prototype Support
  • Responsive Project Handling
  • Warranty Support
  • Controlled Specification Process
Important Note: ETD44 identifies an approximate ferrite-core platform and does not define one fixed power, voltage, current, frequency, inductance, leakage, dielectric strength, insulation class, pinout, or thermal rating. Final capability depends on converter topology, switching waveform, electrical stress, insulation coordination, thermal environment, PCB layout, mechanical installation, compliance requirements, and customer-validation conditions.
