APW7116规格书详情
General Description
The APW7116 integrates Dual PWM buck controllers and an internal linear regulator for DDR memory and MCH power solution. The two synchronous PWM buck controllers drive four N-channel MOSFETs for DDR memory supply voltage (VDDQ) and MCH regulator. The internal regulator is designed to track at the half of the reference voltage with sourcing and sinking current for DDR memory termination regulator (VTT).
Features
• Provide Synchronous Rectified Buck PWM Controllers for VDDQ and VMCH
• Integrated Power FETs with VTT Regulator Source/Sink up to 2.0A
• Drive Low Cost N-Channel Power MOSFETs
• Internal 0.8V Reference Voltage for Adjustable VDDQ and VMCH
• Thermal Shutdown
• VTT Tracks at Half the Reference Voltage
• Fixed Switching Frequency of 250kHz for VDDQ and VMCH
• Over-Current Protection and Under-Voltage Protection for VDDQ and VMCH
• Fully Complies with ACPI Power Sequencing Specifications
• 180 degrees Phase Shift between VDDQ and VMCH
• Power-OK Function for VDDQ and VMCH
