EVBUM2356DB - NCP1034 Buck Converter Evaluation Board User's Manual
ON Semiconductor
This evaluation board user’s manual describes high voltage, high
power and high efficiency DC/DC buck converter featuring the
NCP1034.
The NCP1034 is voltage mode PWM controller for a high voltage
synchronous buck. The controller drives two external N-MOSFETs
with programmable frequency up to 500 kHz for wide applications
range. The IC is able to be synchronized by external signal or is able to
synchronize other ICs that simplify design of system level filter.
The output voltage can be set as low as 1.25 V. Besides system and
drivers UVLO there is an external UVLO that can be set to user value.
Over current protection uses low side MOSFET RDSON as sensing
resistor, which has no impact on efficiency. Current limit protection
uses a hiccup mode. These protections provide application additional
security level.
