The G2228 is a high efficiency single inductor Buck-Boost converter which can supply the load current up to 1.5A. It provides auto-transition between Buck and Boost Mode. The G2228 operates at 2.4MHz switching frequency in CCM. DC/DC converter operates at Pulse-Skipping Mode at light load. The output voltage is programmable using an external resistor divider, or is fixed to 3.3V internally. The load is disconnected from the VIN during shutdown.
