Dc-Dc Converter series offer IGBT gate driver power benefits
The devices are suited to provide an isolated gate drive for both industrial and clean energy applications, such as wind turbines and solar panels.
The VQA series of dc-dc converters operates efficiently at high frequencies (approx. 20 kHz) over an industrial operating temperature range of -40~85°C and come in a compact, internally-potted 8-pin SIP case measuring 19.5 x 9.8 x 12.5 mm.
Of particular relevance to IGBT gate drivers is the VQA series’ ability to isolate and convert power from the main dc bus voltage, making them ideal for IGBT gate drivers that do not contain a built in power supply.
In high side gate drivers, the VQA series’ isolation functionality addresses the problems associated with a constantly changing emitter potential. And, in low side IGBT gate drivers, it eliminates potential ground loop noise problems.
Typical applications incorporating IGBT gate drivers that require an isolated dc-dc converter include photovoltaic panels, solar inverters, servo systems, and pump controllers.
The VQA series is rated up to 2 W and provides nominal inputs of 12, 15, and 24 Vdc. Dual independent outputs of 15/-8, 15/-8.7, and 17/-8.6 Vdc are available.
Availability
The VQA series is available immediately with prices starting at $6.87 per unit for 500 units trough distribution.
