RF6590 Power Management IC

The RF6590 is a power management IC designed for use in transceiver applications, consisting of three low-voltage, high-efficiency, low-ripple DC to DC buck converters and two low-noise LDOs. Using the RF6590 in handset applications can reduce transceiver battery current by up to 50%. Each DC to DC converter has a PWM and a PFM controller to enhance efficiency at light load current conditions. Over-current protection is employed to protect the device during a fault mode.
