Overview
The NCP5351DR2 is a dual MOSFET gate driver optimized for synchronous buck converter applications. It integrates high-side and low-side drivers to control power MOSFETs. The device operates with a supply voltage range of 4.5 V to 20 V. It features independent inputs for high-side and low-side control, allowing for flexible PWM signal integration. The component is housed in an SOIC-8 package and is designed for efficient switching performance in DC-DC conversion topologies.
Feature Summary
- Optimized for driving gates of both high-side and low-side power MOSFETs in synchronous buck converters
- Integrates dedicated high-side and low-side driver channels within a single compact package
- Supports independent input signals for precise control of switching sequences
Applications
- Synchronous buck DC-DC converters
- Point-of-load (POL) power regulation modules
- General-purpose half-bridge driver circuits
Procurement Notes
Verify the specific suffix 'DR2' against the manufacturer's current datasheet to confirm packaging details and availability status. Ensure the ordering part number matches the required tape-and-reel specifications for automated assembly processes. Cross-reference the RoHS compliance status with the latest environmental declarations provided by onsemi.
Selection Notes
Select this component when designing synchronous buck converters requiring integrated high-side and low-side drive capabilities. The SOIC-8 package offers a balance between thermal performance and board space efficiency. Consider the 20 V maximum supply voltage limit when selecting bootstrap capacitors and ensuring compatibility with the target logic input levels.
Part Context
This component belongs to the NCP53xx series of gate drivers from onsemi, which are specialized for power management applications. The series focuses on providing robust driving capabilities for power switches in various DC-DC converter architectures. The NCP5351 specifically targets synchronous rectification needs in modern power supplies.
Replacement Considerations
Check for direct pin-compatible alternatives within the NCP53xx family or other onsemi half-bridge drivers. Verify that any substitute maintains the same SOIC-8 footprint and electrical characteristics suitable for synchronous buck topologies.
