ISL6560CBZ

微处理器核心电压调节两相降压PWM控制器 Microprocessor CORE Voltage Regulator Two-Phase Buck PWM Controller

Microprocessor CORE Voltage Regulator Two-Phase Buck PWM Controller

The ISL6560 two-phase current mode, PWM control IC together with companion gate drivers, the HIP6601A,

HIP6602A, HIP6603A or HIP6604 and MOSFETs provides a precision voltage regulation system for advanced

microprocessors. Two-phase power conversion is a marked departure from earlier single phase converter configurations previously employed to satisfy the ever increasing current demands of modern microprocessors.
