DA6021中文资料Highly Integrated Power Management IC for New Generation Intel® Atom™ Processor数据手册Renesas规格书

描述 Description

The DA6021 uses a single supply voltage at a wide range of input voltage and provides low noise supplies to all SoC voltage domains, DDR3 memory and many peripherals. The DA6021 integrates 6 high-performance low dropout (LDO) voltage regulators using Renesas' patented Smart Mirror™ technology for very low quiescent current. It includes 11 internal power switches and the control logic for 9 external switching devices. These include inrush current control for platform power distribution simplification.

Six fully-integrated high-efficiency DC/DC buck converters provide current to the Intel® Atom™ platform’s various low voltage domains as well as to the memory and the peripherals. Two buck-boost and one boost converter also supply energy towards the platform. All nine regulators are designed to support an external component height of 1mm. Dependent on the input voltage (single battery cell of 5V DC supply) the buck regulators will run preferably at 6MHz.

特性 Features

• Two high-efficiency buck converters with integrated SVID interface running IMVP-7 protocol. These two quad-phase DC/DC regulators generate the voltages for CPU and graphic cores.
• One dual-phase buck regulator for memory supply supporting DDR3 L and LP memory types
• Three single-phase buck regulators supplying 1.0V, 1.05V and 1.8V towards the platform
• Two buck-boost converters generating 2.85V and 3.3V towards the platform even if the input supply is down to 2.7V
• Boost converter providing 5V towards the USB components
• Three LDOs with fixed output voltage
• Two LDOs with programmable output voltage
• One push-pull LDO used for DDR3 address line termination
• 11 integrated power rail switching devices
• Nine external power rail switching devices controlled by the PMIC
