APW7116
Overview
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.
- 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
