The PowerXR family is comprised of six Pulse-Width Modulated (PWM) step-down DC-DC controllers with a built-in LDO for standby power and GPIOs. The latest addition to the family, XRP7724, adds Pulse Frequency Modulation (PFM) for mobile applications. The 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.
