NCP1034DR2G Description

Short technical summary and product information.

The ON Semiconductor NCP1034DR2G is a high-voltage PWM controller designed for high-performance synchronous buck DC-DC applications. It supports input voltages up to 100V and drives a pair of external N-channel MOSFETs. The switching frequency is programmable from 25 kHz to 500 kHz, allowing for flexibility in tuning efficiency and size.

 

Key features include a precision 1.25V internal reference voltage for precise output regulation, programmable soft-start with prebiased load capability, and programmable overcurrent and undervoltage protection. It also incorporates a hiccup current limit using MOSFET RDS(on) sensing and external frequency synchronization capability.

 

This device is supplied in a 16-pin SOIC package suitable for surface mounting. Its applications include 48V non-isolated DC-DC converters, embedded telecom systems, networking and computing voltage regulators, and distributed point-of-load power architectures.

 

The NCP1034DR2G is designed for robust operation with features like undervoltage lockout and hiccup current limiting, making it suitable for demanding high-voltage power supply designs.
