LXDC Series
μDCDC Converters
Features
zz Low EMI noise and small footprint due to Murata’s
Shown larger than actual size.
inductor-embedded ferrite substrate technology zz High efficiency using synchronous rectifier technology and PFM/PWM auto-select function (forced mode available on some models) zz Input voltage range = 2.3–5.5V zz Load currents available are 600mA, 1A, 2A, and 3A 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 Structure
Capacitor DC/DC IC
zz Any device currently using discrete DC-DC circuits where
downsizing and space-savings are required
zz Cellular Phones, PDAs, Mobile Internet Devices zz Digital Cameras, eBooks, Tablets, W-LAN, BT zz 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.
