NCP4305AMTTWG Description

Short technical summary and product information.

The NCP4305AMTTWG from ON Semiconductor is a sophisticated secondary-side synchronous rectification driver designed for high-efficiency switch mode power supplies (SMPS). It is suitable for various topologies including DCM, CCM flyback, quasi-resonant flyback, forward, and half-bridge resonant LLC converters.

Key features include precise zero current detection, adjustable minimum on-time and off-time with ringing detection, and an adaptive gate drive clamp enabling the use of GaN FETs. The device operates with a voltage range up to 35V and offers a wide operating temperature range of -40°C to 125°C.

With a typical turn-off delay of 12 ns and a rugged current sense pin rated up to 200V, the NCP4305AMTTWG ensures reliable and efficient operation. It also incorporates automatic light-load and disable modes to optimize efficiency across different load conditions. The driver is available in an 8-WDFN (2x2) package, suitable for surface mount applications.

This component is ideal for applications requiring high efficiency, such as notebook adapters, high power density AC/DC power supplies, and LCD TVs.
