I just did the same thing.  2.8V to 3.8V in, 5V out, 50mA.  I used a=20
TPS61222DCK chip.
The chip, 1 inductor, 2 capacitors.
Waiting on parts to come in, so don't have test resuts yet.  But my=20
experience with other TI switchers has been great and webench.com will=20
design/choose components for you.
