NCP5351DG

Overview

The NCP5351DG is a dual-channel synchronous buck power MOSFET driver manufactured by onsemi. It operates with a supply voltage range of 4.75 V to 5.5 V and delivers a peak drive current of 4 A per channel. The device supports switching frequencies up to 2 MHz and features adjustable dead-time control to optimize efficiency. It includes integrated bootstrap diodes, under-voltage lockout protection, and short-circuit protection for robust operation in high-performance DC-DC converter applications.

Feature Summary

Dual-channel architecture designed for synchronous buck converter topologies
Integrated bootstrap diodes eliminate external component requirements
Adjustable dead-time control minimizes cross-conduction losses
Built-in under-voltage lockout and short-circuit protection mechanisms

Applications

High-performance CPU and GPU core voltage regulation modules
Server and workstation motherboard power delivery systems
Industrial equipment requiring stable low-voltage power rails
Telecommunications infrastructure power management units

Procurement Notes

Verify the specific suffix 'DG' corresponds to the SOIC-8 lead-free package configuration. Confirm that the intended application voltage aligns with the specified 4.75 V to 5.5 V operating range. Ensure compatibility with the required switching frequency and thermal dissipation capabilities before finalizing procurement orders.

Selection Notes

Select this component when designing synchronous buck converters requiring independent channel control and high drive current. Consider the integrated bootstrap diode feature to reduce bill of materials count. Evaluate the adjustable dead-time functionality against efficiency targets and switching speed requirements for the specific load profile.

Part Context

This part belongs to onsemi's dedicated gate driver family for power management ICs. It complements other voltage regulators and controllers by providing the necessary interface between logic signals and power MOSFET switches.
