GMT致新 G2224KH1U TDFN3X4-14 高效率单电感自动Buck-Boost  转换器

General Description
The G2224 is a high efficiency single inductor Buck-
Boost converter which can supply the load current up
to 4A. It provides auto-transition between Buck and
Boost Mode. The G2224 operates at 2.4MHz and it
can also be synchronized with external frequency from
2.2MHz to 2.6MHz. DC/DC converter operates at
Pulse-Skipping Mode at light load. The Power Save
Mode can be disabled, forcing the G2224 to operate at
FPWM Mode. 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.
The G2224 is available in TDFN3X4-14 package.
