Development Board Operating Up To 10 MHz for POL DC-DC Conversion

27.11. 2017 | News

Efficient Power Conversion (EPC) announces the availability of the EPC9086 development board, a high efficiency half-bridge development board that can operate up to 10 MHz. The EPC9086 board measures 2” x 2” and contains a 30 V, 16 A EPC2111 enhancement-mode gallium nitride half bridge in combination with the recently introduced PE29102 gate driver from Peregrine Semiconductor.

It is important to note that the outputs of this driver can provide switching transition speeds in the sub-nanosecond range with optimized matched dead time and offers best-in-class propagation delay for hard switching applications up to 40 MHz, thus enabling the high performance of GaN power transistors. The PE29102 provides minimum pulse widths of 5 ns and is offered as a 2 x 1.6 mm flip chip die, enabling a small form factor power stage for high duty cycle power conversion at high frequency.

The EPC9086 has been evaluated in a 12 V to point-of-load DC-DC converter application and achieved efficiency levels of 86% at 10 A when switching at 5 MHz and over 80% when switching at 10 MHz.
