Utilizing switching technology, the models are footprint compatible with TO-220 package LM78XX and LM79XX model regulators and unlike linear regulators, do not require a heat sink.

The encapsulated VX78 series and open frame VXO78 series, suited for positive or negative output applications, both offer 500 mA and 1 A output current options and have no-load input currents as low as 0.2 mA. Packaged in a 3 pin SIP footprint, the encapsulated models measure 11.60 x 7.55 x 10.16 mm, while the open frame models have dimensions of 10.00 x 7.20 x 11.00 mm.

 

The 500 mA series accept a range of input voltages up to 4.75 to 36 Vdc, while the 1 A series accommodate input voltage ranges up to 6 to 36 Vdc. Nominal output voltages of 3.3, 5, 9, 12, or 15 Vdc, are also available depending upon the series. Operating temperatures for all models range from -40 up to +71°C at full load, derating to 60% load at +85°C.

 

These non-isolated DC/DC converters also feature low ripple and noise, continuous short circuit protection, and UL 60950-1 and CSA safety certifications, along with the CE mark. All models carry a minimum MTBF of 2,000,000 hours at +25°C ambient, calculated per MIL-HDBK-217F.

 

Prices start at $2.09 (100) through distribution.
