NCP5162
General Purpose
Synchronous Buck Controller
The NCP5162 is a synchronous dual N−Channel buck controller designed to provide unprecedented transient response for today’s demanding high−density, high−speed logic. It operates using a proprietary control method which allows a 100 ns response time to load transients. The NCP5162 is designed to operate over a 9−16 V range (VCC) using 12 V to power the IC and 5.0 V as the main supply for conversion.
The NCP5162 is specifically designed for high performance core logic. It includes the following features: 0.8% output tolerance, VCC monitor, and programmable Soft Start capability. The NCP5162 is available in a 16 pin surface mount package.
Features
• Dual N−Channel Design • Excess of 1.0 MHz Operation • 100 ns Transient Response • 2.0 A Gate Drivers • 1.02 V Reference Voltage with 0.8% Tolerance • 5.0 V & 12 V Operation • Remote Sense • Programmable Soft Start • Lossless Short Circuit Protection • VCC Monitor • V2™ Control Topology • Overvoltage Protection
