【Product Basic Introduction】Small body and high energy: compact push-pull transformers revolutionize power supply design

In the world of electronic engineering, which pursues miniaturization and high performance, isolated power transformers act as the 'guardian saints' of circuits, silently protecting devices and personnel from high voltage threats, while eliminating electronic noise and ensuring stable system operation.

As industrial automation, energy storage systems, and portable devices become increasingly space-demanding, compact push-pull transformers are becoming the new favorite in power supply design.

Suzhou VOOHU Electronic Technology Co., Ltd. launched a compact push-pull transformer to reconstruct the power isolation scheme in millimeter size.

The core advantages of compact push-pull transformers are:

Ultra-small volume:the minimum size is only 6.55*9.85*4.00mm (WHST06E series), and the maximum size is 8.80*13.00*6.60mm (WHST06D series), freeing up key space for PCB layout;

Power density: supports 1700mA output current, stable operation in a wide temperature environment of -40°C~125°C, and adapts to harsh industrial scenarios;

Safety barrier:insulation withstand voltage up to 6000VDC, 8mm creepage distance to meet the requirements of 1000V high voltage system

Technological breakthrough:ring winding and efficient coupling

The ring tight winding structure achieves a > coupling coefficient of 95%, significantly reducing magnetic loss and improving energy transmission efficiency. With a push-pull circuit design, it supports 200~700kHz high-frequency switching, effectively suppresses electromagnetic interference (EMI), and provides a "pure" power supply for precision circuits

Flexible voltage conversion for multiple purposes

With a multi-winding center tap, it supports a wide range of 1:1 to 1:5.0 turn-ratio configurations:

Co-voltage isolation (5V→5V)

Boost Conversion (3.3V→12V)

Multiple outputs (e.g. RS-485/CAN bus isolated power supply)

Globally certified for safe and secure safety

Complies with IEC 62368-1 safety standards, provides both basic and reinforced insulation options, and has passed RoHS environmental protection certification, helping products quickly enter the global industrial market.

Application Scenario: The "Big Stage" of Small Devices

Industrial automation: provide micro-isolated power supply for PLC control modules and sensor networks;

New energy system: realize high and low voltage safety isolation in BMS battery management and energy storage converter;

Communication equipment: Provide stable isolation power supply for 5G micro base stations and RS-485/CAN interfaces;

Portable healthcare: Enabling high-density power supply design for handheld diagnostic instruments, monitors, and other devices.
