Description
The Bel V7BC-16F2Ax modules are a series of non-isolated DC/DC converters that can deliver up to 16A of output current with full load efficiency of 94% at 3.3V output. These modules provide precisely regulated voltage These modules have a sequencing feature that enables designers to implement various types of output voltage sequencing when powering multiple voltages on a board. Their open-frame construction and small footprint enable designers to develop cost and space-efficient solutions. Standard features include remote ON/OFF, programmable output voltage and over current protection. Part Selection Output Voltage Input Voltage Max. Output Current Max. Output Power Typical Efficiency Model Number Active Low Model Number Active High Note: Add “G” suffix at the end of the model number to indicate “Tray Packaging”. Absolute Maximum Ratings Parameter Min Typ Max Notes Input Voltage (continuous) -0.3V - 5.8V Output Enable Terminal Voltage -0.3V - 5.8V Sequencing Voltage 1 -0.3V - Vin Ambient Temperature -40°C - 85°C Storage Temperature -55°C - 125°C Notes: All specifications are typical at 25°C unless otherwise stated. 1. V7BC-16F2Ax series of modules include a sequencing feature that enables users to implement various types of output voltage sequencing in their applications. This is accomplished via an additional sequencing pin. When the sequencing feature is not used, tie the SEQ pin to Vin. V7BC-16F2Ax Series
