Intel ER5312D

Description

The ER5312D provides the benefits of high switching frequency with the flexibility to optimize the design for footprint or efficiency.The 4 MHz operation allows for the use of a tiny inductor and MLCC capacitors. It also enables a very wide control loop bandwidth providingexcellent transient performance and reduced output impedance. The internal compensation is designed for unconditional stability.Three VID output voltage select pins provide seven pre-programmed output voltages along with an option for external resistor divider.Output voltage can be programmed on-the-fly to provide fast, dynamic voltage scaling with smooth transitions between programmed outputvoltages.
