DC-DC Converters

HALO Electronics DC-DC Converters are 1W and 2W isolated converters that provide a compact surface mount solution. The DC11 and DC21 converters are designed with 1.5KV_DC isolation voltage, and the DC13 converters are designed with 3KV_DCisolation voltage. The DC-DC converters feature high efficiency and low ripple noise and are designed to operate from -40°C to +105°C temperature range. These converters offer functional insulation and provide continuous short-circuit protection. Both 1W and 2W versions are available in industry-standard SMD packages.
