GENERAL DESCRIPTION
The XRP7724 is a quad channel Digital Pulse Width Modulated (DPWM) Step down (buck) controller.
A wide 4.
75V to 5.
5V and 5.
5V to 25V input voltage dual range allows for single supply operation from standard power rails.
With integrated FET gate drivers, two LDOs for standby power and a 105kHz to 1.
23MHz independent channel to channel programmable constant operating frequency, the XRP7724 reduces overall component count and solution footprint and optimizes conversion efficiencies.
A selectable digital Pulse Frequency Mode (DPFM) capable of better than 80% efficiency at light ...
