EPC Space introduces EPC7C010 and EPC7C011 half-bridge buck platforms for radiation-hardened applications

Half-bridge eGaN buck designs deliver high efficiency and flexibility, supporting next-generation aerospace systems with adjustable switching frequencies

ANDOVER, MA, UNITED STATES, March 31, 2026 /EINPresswire.com/ -- EPC Space, a manufacturer of radiation-hardened, high-performance, and enhanced-reliability GaN discrete transistors, integrated circuits, and modular devices, today announced two new additions to its family of demonstration and evaluation boards supporting applications including half-bridge connected point-of-load (POL) converter power stages, single- and multi-phase motor drivers, and Class-D single- and full-bridge stages.

The EPC7C010 is a 100 V / 20 A high-efficiency half-bridge power circuit configured as a buck (step-down) switching regulator output stage. This board utilizes the EPC7004B GaN HEMT as the power switching elements and the FBS-GAM01P-R-PSE module as the low- and high-side gate drivers.

The EPC7C011 is a 200 V / 10 A high-efficiency half-bridge power circuit configured as a buck (step-down) switching regulator output stage. This board utilizes the EPC7007B GaN HEMT as the power switching elements and the FBS-GAM01P-R-PSE module as the low- and high-side gate drivers.

Both boards are optimized for 350 kHz operation as delivered, but support flexible switching frequencies from 50 kHz to 1.5 MHz with appropriate output filter component adjustments.

Typical performance highlights:

• EPC7C010: Peak efficiency of 94.7% (at VIN < 50 V) and ≥ 87.5% across 2 A < Iload < 20 A
• EPC7C011: Peak efficiency of 96.6% (at VIN < 100 V) and ≥ 92.5% across 2 A < Iload < 10 A

Both evaluation boards include adjustable dead-time insertion and offer multiple options for output filter capacitors (type and physical size) to support end-user customization. They also feature galvanic isolation between the low- and high-side gate drivers to ensure balanced propagation delays. A logic-compatible PWM input signal is provided via an SMA-style connector on both boards.

“These new half-bridge eGaN evaluation boards demonstrate how high-frequency GaN power stages can improve efficiency and power density while offering the flexibility designers need for demanding aerospace and high reliability applications,” said Bel Lazar, EPC Space CEO.

A comprehensive operating guide - including connection instructions, typical efficiency curves, switching waveform measurements, schematic and bill of materials (BOM) -is available for download on the EPC Space website.
