CS5166H Datasheet, PDF (1/25 Pages) Cherry Semiconductor Corporation – 5-Bit Synchronous CPU Controller with Power-Good and Current Limit

CS5166H
5−Bit Synchronous CPU
Controller with Power Good
and Current Limit
The CS5166H is a synchronous dual NFET buck controller. It is
designed to power the core logic of the latest high performance CPUs. It
uses V²â„¢ control method to achieve the fastest possible transient
response and best overall regulation. It incorporates many additional
features required to ensure the proper operation and protection of the
CPU and power system. The CS5166H provides the industry’s most
highly integrated solution, minimizing external component count, total
solution size, and cost.
The CS5166H is specifically designed to power Intel’s Pentium^®II
processor and includes the following features: 5−bit DAC with 1.0%
tolerance, Power Good output, adjustable hiccup mode overcurrent
protection, V_CC monitor, Soft Start, adaptive voltage positioning,
overvoltage protection, remote sense and current sharing capability.
The CS5166H will operate over a 4.15 to 20 V range using either
single or dual input voltage and is available in a 16 lead wide body
surface mount package.
