The NCP5220MNR2G from ON Semiconductor is a versatile 3-in-1 power controller solution, specifically engineered for MCH and DDR memory power supplies. This IC combines the efficiency of PWM controllers for VDDQ and MCH core voltage with the simplicity of a linear regulator for VTT termination voltage.
Key features include two synchronous PWM buck controllers capable of driving external N-Channel FETs for DDR memory (VDDQ) and MCH regulators. The VTT termination regulator is designed to track at half the reference voltage, with sourcing and sinking current capabilities up to 2.0 A. The device operates within a voltage range of 5V to 12V and has an operating temperature range of 0°C to 70°C.
Protective features are integrated to ensure reliability, including soft-start circuitry, undervoltage monitoring, overcurrent protection for DDQ and VTT regulators, short circuit protection, and thermal shutdown. The NCP5220MNR2G operates at a fixed switching frequency of 250 kHz for VDDQ and VMCH, with a doubled frequency of 500 kHz for the VDDQ controller in standby mode to optimize efficiency. It fully complies with ACPI Power Sequencing Specifications.
The device is housed in a space-saving 20-DFN (6x5) package with an exposed pad for enhanced thermal performance. It is available in a Surface Mount configuration, supplied in Tape & Reel packaging with a standard quantity of 2500 units.
