The NCP1034 is a high voltage PWM controller designed for high performance synchronous Buck dc-dc applications. The NCP1034 drives a pair of external N-MOSFETs using a programmable switching frequency up to 500 kHz which allows flexibility to tune the operation of the IC to meet system level requirements. An external synchronization feature allows the simplification of system level filter design.
Input voltage up to 100V External Frequency Synchronization Programmable switching frequency up to 500 kHz Wide input voltage to be used with +48V or +60V input Ability to use larger size FETs for increased efficiency Excellent system level accuracy across temperature Ability to sync to external frequency or output a sync pulse Optimization for efficiency and size
