The PW2228A 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 PW2228A
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.
The PW2228A is available in TDFN3X3-10 package.
