Controllers | ADP3212A
概览
7-Bit, Programmable, 3-Phase, Mobile CPU Synchronous Buck Controller
- Notebook power supplies for next-generation Intel® processors
- Single-Chip Solution
- Fully compatible with the Intel® IMVP-6.5 specifications
- Selectable 1-, 2-, or 3-phase operation with up to 1 MHz per phase switching frequency
- Phase 1 and phase 2 integrated MOSFET drivers
- Input voltage range of 3.3V to 22V
- Guaranteed ±8 mV worst-case differentially sensed core voltage error over temperature
- Automatic power-saving mode maximizes efficiency with light load during deeper sleep operation
- Active current balancing between output phases
- Independent current limit and load line setting inputs for additional design flexibility
- Built-in power-good blanking supports voltage identification (VID) on-the-fly (OTF) transients
- 7-bit, digitally programmable DAC with 0.3V to 1.5V output
- Short-circuit protection with programmable latchoff delay
- Clock enable output delays the CPU clock until the core voltage is stable
- Output power or current monitor options
- 48-lead QFN 7x7mm (ADP3212A), 48-lead QFN 6x6mm (NCP3218A)
- These are Pb-free devices
- Fully RoHS compliant
