HB04U15S05Q (C&D TECHNOLOGIES)

The HB04U Series is a low-cost, high-isolation voltage, unregulated, single and dual output DC/DC converter. The dielectric withstand characteristics of each converter is tested in production to ensure barrier integrity. The HB04U Series uses advanced circuit design and packaging technology to realize superior reliability and performance. A 100kHz driven push-pull oscillator is used to ensure stable frequency and non-saturating operation of the input stage. This means there are no high peak voltages or currents like other design topologies, which can reduce unit reliability. Reliability is further enhanced by the use of MOSPOWER transistors. These rugged devices permit higher frequency operation with less complicated drive circuitry than is possible with bipolar power transistors. Reduced parts count adds to the reliability of the HB04U Series. The high efficiency of the HB04U Series means less internal power dissipation. With less heat to dissipate, the HB04U Series can operate over a wider ambient temperature range with no degradation of reliable operation.
