XRP7720
Quad Output Universal Customizable PMIC with PFM
FEATURES AND BENEFITS
Programmable Power Benefits
 Fully Configurable
 Output set point
 Feedback compensation
 Frequency set point
 Under voltage lock out
 Reduced Development Time with
XRP7720-DEV
 Configurable and re-configurable for
different Vout, Iout, Cout, and Inductor
values
 No need to change external passives for a
new output specification.
 Higher integration and Reliability
 Many external circuits used in the past
can be eliminated thereby significantly
improving reliability.
 Pin Compatible to XRP7724
 Provides easy migration path to a full
featured programmable power
management system with dynamic
control and telemetry
