NCP4307AASNT1G Description

Short technical summary and product information.

The NCP4307AASNT1G from On Semiconductor is a versatile secondary-side synchronous rectification driver tailored for high-efficiency switch mode power supplies (SMPS). It is designed to control a synchronous rectification MOSFET and can be utilized in various topologies, including DCM, CCM flyback, quasi-resonant flyback, and forward converters.

Key features include a precise turn-off threshold, extremely low turn-off delay time (typically 15 ns), and high sink/source drive capability (7 A / 2 A). The device operates over a voltage range up to 35V and has an operating temperature range of -40°C to 125°C (TJ). It also incorporates features like internal minimum on-time with reverse current protection and minimum off-time with ringing detection, ensuring reliable operation.

This driver supports self-supply capability, allowing for high-side configurations or low output voltage SMPS without an auxiliary winding. It also features an automatic light-load disable mode for improved efficiency at lighter loads. The NCP4307AASNT1G is available in a 6-TSOP package and is surface-mounted.

Applications for this component include notebook adapters, high power density AC/DC power supplies, LCD TVs, and other SMPS requiring high efficiency.
