| NON-ISOLATED DC/DC CONVERTERS 5.0 V Input 1.2 V-3.3 V/15 A Output V7PF-15B1AC * * * * * Non-Isolated Fixed Frequency (300 kHz) Remote On/Off Low Cost Power Good Output Signal (open collector) * * * * Wide Trim Range Under-voltage Lockout (UVLO) OCP/SCP Converter Can Sink and Source Current Description The Bel V7PF-15B1AC is part of the low cost non-isolated dc/dc converter series. The modules use a SIP package for ease of layout and space savings. The output is closely regulated and can be trimmed from 1.2 V to 3.3 V. The efficiency is typically 93% at 3.3 V output at full load. Typical features include remote on/off, under-voltage lockout, over-current protection and short circuit protection. Part Selection Output Voltage 1.2 V - 3.3 V Input Voltage 5V Max. Output Current 15 A Max. Output Power 49.5 W Typical Efficiency 93% Model Number V7PF-15B1AC Note: Add "0" suffix at the end of the model number to indicate "Tube Packaging", and "G" for "Tray Packaging".

Power good delay time is the time from output voltage in full regulation to power good asserted. 2. The power good signal is an open collector output. When the output of the module is higher than 90% of the nominal set point, the power good pin is high.
