Description

The CS5159DR16 is a 5-bit 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, allowing a 100 ns response time to load transients. The CS5159DR16 is designed to operate over a 4.25-16 V range (VCC) using 12V to power the IC and 5.0V or 12V as the main supply for conversion.
