Description
Bootstrap. A capacitor and a resistor in series connected between this pin and DC/DC
converter’s SW node is required to charge storage capacitor.
Supply Voltage. The MP201 operates from a +4.5V to +18V input rail. Input decoupling
capacitor is needed to decouple the input rail.
Feedback to set release voltage.
System Ground. This pin is the reference ground of the regulated output voltage.
For this reason care must be taken in PCB layout. Suggested to be connected to
GND with copper and vias.
Feedback to set storage voltage.
Open drain output to indicate dying gasp operation is active.
Connect to storage capacitor for dying gasp storage and release operation.
Internal Supply. A 2.2nF ceramic capacitor is required for decoupling.
