CS51313
Synchronous CPU
Buck Controller Capable
of Implementing Multiple
Linear Regulators
The CS51313 is a synchronous dual NFET Buck Regulator
Controller. It is designed to power the core logic of the latest high
performance CPUs. It uses the V2™ 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 CS51313
provides the industry’s most highly integrated solution, minimizing
external component count, total solution size, and cost.
The CS51313 is specifically designed to power Intel’s Pentium® II
processor and includes the following features: 5−bit DAC with 1.2%
tolerance, Power Good output, overcurrent hiccup mode protection,
overvoltage protection, VCC monitor, Soft Start, adaptive voltage
positioning and adaptive FET non−overlap time. A precision reference
trimmed to 1.0% is also externally available for use by other
regulators. The CS51313 will operate over an 8.4 V to 14 V range and
is available in 16 lead narrow body surface mount package.

3. The IC power dissipation in a typical application with VCC = 12 V, switching frequency fSW = 250 kHz, 50 nc MOSFETs and RθJA = 115°C/W
yields an operating junction temperature rise of approximately 52°C, and a junction temperature of 77°C with an ambient temperature
of 25°C.
