Product Overview
Product Description
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. The output voltage can be precisely regulated using the internal 1.25 V reference voltage for low voltage applications. Protections such as under voltage lockout and hiccup current limit are provided to give required system level security in the event of a fault.
