Description
This document describes how the NCP5181 driver can beimplemented in a ballast application. The scope of thisevaluation board user’s manual is to highlight the NCP5181driver and not to explain or detail how to build an electronicballast.The NCP5181 is a high voltage power MOSFET driverproviding two outputs for direct drive of two N-channelpower MOSFETs arranged in a half-bridge (or any otherhigh-side + low-side topology) configuration.It uses the bootstrap technique to ensure a proper drive ofthe high-side power switch. The driver works with twoindependent inputs to accommodate with any topology(including half-bridge, asymmetrical half-bridge, activeclamp and full-bridge).
Typical applications
- Full−bridge Converters
- Any Complementary Drive Converters (asymmetrical half−bridge,active clamp)
- High Power Energy Management
- Half−bridge Power Converters
- Bridge Inverters for UPS Systems
