MP5475 Description
The MP5475 is a plete power management IC (PMIC) that integrates four high efficiency step-down DC/DC converters and a flexible logic interface. The integrated DC/DC converters provide constant-on-time (COT) control to achieve fast transient response. In addition, the 1MHz switching frequency (fSW) minimizes the external inductor and capacitor size.
