LXDC Datasheet, PDF (1/2 Pages) Murata Manufacturing Co., Ltd. – Low EMI noise and small footprint due to Murata’s inductor-embedded ferrite substrate technology

Structure
Shown larger than actual size.
Capacitor
DC/DC
IC
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.
Downsizing Advantage
Discrete Solution
2HL or 2HN
Series (0.6A)
LXDC Series
μDCDC Converters
Features
zzLow EMI noise and small footprint due to Murata’s
inductor-embedded ferrite substrate technology
zzHigh efficiency using synchronous rectifier technology and
PFM/PWM auto-select function (forced mode available on
some models)
zzInput voltage range = 2.3–5.5V
zzLoad currents available are 600mA, 1A, 2A, and 3A
zzFixed 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)
zzSwitching frequency = 3.0, 3.3, 4.0, or 6MHz (see back)
zzOperating temperature range = -40 to +85°C
Applications
zzAny device currently using discrete DC-DC circuits where
downsizing and space-savings are required
zzCellular Phones, PDAs, Mobile Internet Devices
zzDigital Cameras, eBooks, Tablets, W-LAN, BT
zzPortable Game Consoles, Music Players, etc.
