The LXDC2UR series is a low power step-down DC-DC converter, which is suitable for a space-limited or anoise-sensitive application. The device utilizes an inductor-embedded ferrite substrate, and the substrateeliminates radiated EMI noise and conduction noise efficiently.By just putting this device, it can be used as a high performance LDO replacement. Its low noise feature and easyto assembly feature assures reliable power supply quality.The device works in PFM mode at light load and it extends the battery life by reducing quiescent current. Atheavy load, its control mode changes to PWM mode automatically and it keeps high efficiency using synchronousrectifying technology. If only heavy load current operation is needed, PWM forced mode is available. In PWMforced mode, ripple noise is reduced. In shutdown mode, the current consumption is up to 1uA.
Low EMI noise and small footprint (5.75mm2 ) using inductor-embedded ferrite substrate
Up to 90% high efficiency using synchronous rectifier technology at 6MHz operation
PFM/PWM automatic mode switching function for high efficiency operation over full current range
