Description

  • DN06073/D, Reference design is proposed for a +24V input industrial application where there is a need to step-down the voltage to +3.3V @ 5A. The requirement specified a large electrolytic input capacitance and also to utilize electrolytic capacitors on the output. Target efficiency is >85%. The PCB for the NCP3020 is a 2-layer board for use in applications up to 50W. The synchronous buck converter uses voltage mode control, which can be compensated externally with a transconductance amplifier. The soft start time is fixed. The NCP3020 demonstration board is a flexible design allowing the use of electrolytic capacitors or ceramic capacitors.
