12DZ Series – Low-Power DC/DC Converters Offer 2:1 Input Voltage Range

12DZ and 12DZ-2W in the popular single-in-line package expands the DC/DC converter portfolio of YDS (Distributor: MSC Vertriebs GmbH) with low-power models that offer wide input voltage ranges of 4.5-9 V, 9 -18 V or 18-36 V. With high efficiency and continuous short circuit protection these converters deliver an output power of 1 W and 2 W respectively over an ambient temperature range from -40 °C to +85 °C.

The series 12DZ and 12DZ-2W include standard models that generate output voltages of 5V, 9 V, 12 V, 15 V or 24 V. In production quantities other voltages can be supplied to customer specifications. The output voltage has an accuracy of ±5% and is regulated to ±0.5% over the entire input voltage range. Load regulation is ±1.5%. Ripple and noise does not exceed 100 mVpp or 1% of Vout respectively. Switching frequency is 100 kHz. Transient response to load steps of 50% is 350 µs.

The 12DZ and 12DZ-2W series guarantee an isolation of 3000 VDC between input and output and a lifetime (MTBF according to MIL-HDBK-217F) of 1.5 million hours minimum. These specifications make the low-cost converters optimum solutions for applications that must consider widely varying input voltages and/or need short circuit protection. They are a perfect upgrade for conventional 12D series models and similar converters from other brands.
