The Bel V7PB-06B series modules are non-isolated, step down DC/DC power converters that operate from a nominal 5V
source. These converters are available in a range of output voltages from 1.5V to 3.3V. They are packaged in an industry
standard single-in-line footprint and provide a maximum 6A output. Standard features include remote on/off, over current
protection and output voltage adjust. Optional features include remote sense and industrial temperature range. These
products may be used almost anywhere low-voltage silicon is employed and a 5V source is available. Typical applications
include file servers, routers, line cards and other computing and communications equipment.

Use beyond the maximum ratings may cause a reliability degradation of the DC/DC
converter or may permanently damage the device.
Note: Input capacitance 330F/10V, ESR = 0.03
max at 100kHz @ 25 C.
1. With simulated source impedance of 500nH, 5Hz to 20MHz.
