onsemi NCP4306: High Efficiency SMPS Synchronous Rectification Driver

The onsemi NCP4306 is a high-performance driver designed to optimize synchronous rectification in switch-mode power supplies (SMPS). It offers advanced features for achieving high efficiency across various topologies, including DCM, CCM, quasi-resonant flyback, forward, and resonant LLC converters. This driver is engineered to manage synchronous rectification MOSFETs, ensuring efficient power conversion at both full and light load conditions.

Key Features

Precise zero current detection and low turn-off delay.
Adjustable or fixed minimum on-time and off-time with ringing detection.
High peak current sink/source drive capability (7A/2A).
Supports GaN transistors and operates up to 35 V VCC.
Automatic light-load disable mode for reduced consumption.

Typical Applications

Notebook Adapters
High Power Density AC/DC Power Supplies (e.g., Cell Phone Chargers)
LCD TVs
General SMPS requiring high efficiency.
