power and GPIOs. The XRP7704, XRP7708, XRP7713, XRP7714, and XRP7740 devices provide a complete power management
solution in one IC and are fully programmable via the included I²C serial interface. Independent Digital Pulse-Width Modulator
(DPWM) channels regulate output voltages and provide all required protection functions such as current limiting and over-
voltage protection.

Benefit
•
•
•
•
•
•
Reduces design effort by using simple GUI
instead of changing hardware
Reduces risk by enabling customer to repair/
upgrade power supply when already at
end-customer location
Use common platform across multiple
customer designs
Replaces cumbersome discrete solutions,
reduces footprint and cost of passive
components
Accelerates time to market from first meeting
to production in as little as 2 weeks
Enable wide range of design engineers to
leverage their level of expertise for optimal
design
