CS5157H中文资料CPU 5-Bit Synchronous Buck Controller数据手册ONSEMI规格书

描述 Description

The CS5157H is a 5-bit synchronous dual N-Channel buck controller. It is designed to provide unprecedented transient response for today's demanding high-density, high-speed logic. The regulator operates using a proprietary control method, which allows a 100ns response time to load transients. The CS5157H is designed to operate over a 4.25-20V range (VCC) using 12V to power the IC and 5V or 12V as the main supply for conversion. The CS5157H is specifically designed to power Pentium ? II processors and other high performance core logic. It includes the following features: on board, 5-bit DAC, short circuit protection, 1.0% output tolerance, VCC monitor, and programmable soft start capability. The CS5157H is available in 16 pin surface mount.
