Product Descriptions
The AVO250-48S28B is a single output DC/DC converter with standard eighth-
brick form factor and pin configuration. It delivers up to 9A output current with
28V output.
Ultra-high 93% efficiency and excellent thermal performance makes it an ideal
choice for using in telecommunication and datacom applications and can operate
under an ambient temperature range of -40 ^OC ~ +85 ^OC, with full power
available when the baseplate of the unit is kept below 100 ^OC.
Applications
This family of units has been specifically designed to support the rigors of the
supply of power to RF Power Amplifiers in small-cell, low power applications in
Telecommunication applications.
The small form-factor, baseplate construction are exceptionally well suited for
such applications where small space and contact-cooling are essential attributes
required of the DCDC converter. Add this to the wide output trim range of 18V to
32V means that this unit is extremely versatile in the applications that it can
address.
Typically, this unit is used along side a member of the AVD (1/16^th brick) family
of DCDC converters to provide the lower voltage required to supply power to
digital circuitry present in such RF Power-Amplifier applications.
