CS5158数据手册ONSEMI中文资料规格书

描述 Description

The CS5158 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 CS5158 is designed to operate over a 4.25-16V range (VCC) using 12V to power the IC and 5V as the main supply for conversion. The CS5158 is specifically designed to power Pentium â II processors and other high performance core logic. It includes the following features: on board, 5-Bit DAC, short circuit protection, 0.8% output tolerance for the 01111 DAC code (1.3V) and 1% for the remaining DAC codes, VCC monitor, and programmable soft start capability. The CS5158 is available in 16 pin surface mount.
