high ? powered white LED. The buck ? boost is implemented in an
H ? bridge topology and has an adaptive architecture where it operates
in one of three modes: boost, buck ? boost, or buck depending on the
input and output voltage condition. This device has been designed
with high ? efficiency for use in portable applications and is capable
of driving in DC up to 900 mA into a high power LED for flashlight /
torch applications. To protect the device cycle ? by ? cycle current

limiting and a thermal shutdown circuit have been incorporated as
well as output over ? voltage protection. The 700 kHz switching
frequency allows the use of a low value 4.7 m H and ceramic
capacitors. The NCP5030 is housed in a low profile space efficient
3x4 mm thermally enhanced WDFN.
