zz
Fixed output voltage = 1.0V, 1.2V, 1.35V, 1.5V, 1.8V, 2.5V,
3.0V, or 3.3V (see product line-up table on back)
zz
Switching frequency = 3.0, 3.3, 4.0, or 6MHz (see back)
zz
Operating temperature range = -40 to +85°C
Applications
zz
Any device currently using discrete DC-DC circuits where
Structure
downsizing and space-savings are required
zz
Cellular Phones, PDAs, Mobile Internet Devices
Capacitor
zz
Digital Cameras, eBooks, Tablets, W-LAN, BT
DC/DC
IC

Portable Game Consoles, Music Players, etc.
Application Circuit
2UR/3EP series
2HL/2HN series
Multilayer process to create
a ferrite substrate with
3-dimensional circuits and
embedded power inductor
I/O via holes through the
ferrite substrate act as
ferrite beads and reduce
conductive noise.
