The CS5165 is a 5-bit synchronous buck controller that provides fast transient response and best overall voltage regulation for managing the power of the next generation low voltage Pentium II processors.
The CS5165 is a synchronous 5-bit NFET buck controller designed to manage power for next-generation low voltage Pentium II processors. It features a V2 control architecture delivering a 100ns transient response and includes an on-board 5-bit DAC with 1% tolerance over temperature. The device offers programmable soft start, FET non-overlap circuitry, and protection against over-voltage and short circuits via a hiccup mode.
| Transient Response | 100ns |
|---|---|
| Package Type | 16 lead SOIC wide body |
| DAC Tolerance | 1% |
| Oscillator Frequency | Up to 1MHz |
The controller delivers a transient response of 100ns.
It is available in a 16 lead SOIC wide body package.
During a short circuit, the controller pulses the MOSFETs in a 'hiccup' mode with a 3% duty cycle until the fault is removed.
