Description
The Bel x7PF-20A1A0 is a new high density open frame non-isolated converter series for space sensitive applications. Each model has a wide input range (10.2V-13.8V) and offers a wide range of output voltage (0.9V - 5.0V) with a 20A load. An external resistor adjusts the output voltage from its pre-set value of 0.9V to any value up to the 5.0V maximum. Typical efficiency is 92% at Vo=5V, Vin=12V at full load. Typical features include remote on/off, under-voltage lockout, over-current protection and short circuit protection. Part Selection Output Voltage Input Voltage Max. Output Current Max.
