Half-bridge eGaN buck designs deliver high efficiency and flexibility, supporting next-generation aerospace and industrial systems with adjustable switching frequencies
Andover, MA, USA – March 31, 2026 – 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.
For pricing, availability, and ordering information for the EPC7C010 and EPC7C011 evaluation boards, please contact EPC Space directly.

EPC Space Introduces High-Accuracy GaN Linear Regulator Evaluation Boards
NewsNew designs offer low dropout operation, tight regulation, and configurable loop compensation for demanding applications
Andover, MA, USA – April 6, 2026 – EPC Space, a manufacturer of radiation-hardened, high-performance, and enhanced-reliability GaN discrete transistors, integrated circuits, and modular devices, today announced two additions to its demonstration/evaluation board lineup supporting applications including rad-hard linear regulators and space control electronics.
The EPC7C023 is a 5A linear regulator that can be user configured as a standard linear regular or a low-dropout voltage (LDO) linear regulator. This evalulation board utilizes the EPC7019G HEMT as the pass element.
The EPC7C024 is a 0.5A linear regulator that can be user configured as a standard linear regular or a low-dropout voltage linear regulator (LDO). This evaluation board utilizes the EPC7014UB HEMT as the pass element.
Both these demonstration boards utilize TL1431 shunt regulator as the controller, and both regulator boards have a preset 5.0Vdc output voltage.
When configured as a standard linear regulator, the input voltage must remain at least 3 V above the output voltage. When configured as an LDO, the bias voltage must be 8.5 Vdc minimum, and the power input may be as low as:
Both boards include provisions for end users to implement various loop compensation schemes and the output voltage may be adjusted using a single resistor. A Kelvin-connected current sense resistor is also provided to enable accurate load current monitorin. An operating guide that contains connection instructions, typical line and load regulation and load-step dynamic performance, schematic and bill of material is available on the EPC Space website.
“With the introduction of the EPC7C023 and EPC7C024 evaluation boards, EPC Space is expanding designers’ access to high-accuracy GaN-based linear regulation solutions tailored for demanding space and high-reliability applications. These boards demonstrate how radiation-hardened GaN devices can enable tight regulation, low dropout performance, and flexible loop compensation in compact architectures – helping engineers accelerate development of next-generation satellite and control electronics power systems, ” said Bel Lazar, EPC Space CEO.
