Description

The EHHD020A0F [Hammerhead™] Series, eighth-brick, low-height power modules are isolated dc-dc converters that provide a single, precisely regulated output voltage over an ultra wide input voltage range of 18-75Vdc. The EHHD020A0F provides 3.3Vdc nominal output voltage rated for 20Adc output current. The module incorporates Lineage Power’s vast heritage for reliability and quality, while also using the latest in technology, and component and process standardization to achieve highly competitive cost. The open frame module construction, available in both surface-mount and through-hole packaging, enable designers to develop cost and space efficient solutions. The module achieves typical full load efficiency greater than 91% at VIN=24Vdc or at VIN=48Vdc. Standard features include remote On/Off, remote sense, output voltage adjustment, overvoltage, overcurrent and overtemperature protection. An optional heat plate allows for external standard, eighth-brick heat sink attachment to achieve higher output current in high temperature applications.
