| Part: | NCP5381 |
| Category: | Power Management => DC-DC Converters => Programmable |
| Description: | 2/3/4-Phase Buck Controller for VR10 and VR11 Pentium IV Processor Applications
The NCP5381 is a two-, three-, or four-phase buck controller which combines differential voltage and current sensing, and adaptive voltage positioning to power Intel's most demanding Pentium IV Processors and low voltage, high current power supplies. Dual-edge pulse-width modulation (PWM) combined with inductor current sensing reduces system cost by providing the fastiest initial response to transient loads thereby requiring less bulk and ceramic output capacitors to satisfy transient load-line requirements.
