cherry semiconductor CS5165H Fast Precise 5-Bit Synchronous Buck Controller for the Next Generation Low Voltage Pentium II Processors handbook
The Cherry Semiconductor CS5165H is a synchronous 5-bit NFET buck controller designed to manage power for next-generation Pentium II processors. It features a unique V2 control architecture that delivers the fastest transient response in the industry at 100ns, along with superior voltage regulation.
The device includes an on-board 5-bit DAC with +1% tolerance over temperature and a programmable soft-start circuit to ensure controlled startup. It also incorporates FET non-overlap circuitry to prevent simultaneous conduction of both MOSFETs. The controller supports operation from single or dual 5V/12V power supplies and includes protection features such as Overvoltage Protection (OVP) and short-circuit hiccup mode.

Questions answered in these manuals
Does the CS5165H require external components for Overvoltage Protection?
No, the OVP feature is part of the V2 architecture and does not require any additional components.
How does the controller handle short circuit conditions?
During a short circuit, the controller pulses the MOSFETs in a 'hiccup' mode with an 8% duty cycle until the fault is removed.
What is the transient response of the CS5165?
The controller delivers a transient response of 100ns.
What package is the CS5165 available in?
It is available in a 16 lead SOIC wide body package.
