Global Mixed-mode Technology G2228 High Efficiency Single Inductor Auto Buck-Boost Converter Features General Description 1.8V ~ 5.5V Input Voltage Operation The G2228 is a high efficiency single inductor Buck- Adjustable Output Voltage from 2.8V to 5.5V Boost converter which can supply the load current up 95% Efficiency DC/DC Converter to 1.5A. It provides auto-transition between Buck and 1.5A Output Current at 3.3V for VIN > 3.6V Boost Mode. The G2228 operates at 2.4MHz Auto-Transition Between Buck and Boost Mode switching frequency in CCM. DC/DC converter Pulse-Skipping Mode at light load for Efficiency operates at Pulse-Skipping Mode at light load. The DC/DC Converter can be set to lower quiescent output voltage is programmable using an external current at light load resistor divider, or is fixed to 3.3V internally. The load Fixed 2.4MHz Frequency and Synchronization is disconnected from the VIN during shutdown. Possible Internal Soft-Start The G2228 is available in WLCSP2X4-8 package.

Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications are not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. 2. Device is ESD sensitive. Handling precaution recommended. The Human Body model is a 100pF capacitor discharged through a 1.5K resistor into each pin. Electrical characteristics (VIN=VINA=3.6V, T =25C, unless otherwise specified) A The device is not guaranteed to function outside its operating conditions. Parameters with MIN and/or MAX limits are 100% tested at +25C, unless otherwise specified.
