Fixed output voltage: 1.2V, 1.5V, 1.8V, 3.0V, 3.3V Internal soft start, 120 s start-up time Current over load and thermal shutdown protection 2. Description The LXDC2UR series is a low power step-down DC-DC converter, which is suitable for a space-limited or a noise-sensitive application. The device utilizes an inductor-embedded ferrite substrate, and the substrate eliminates 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 easy to 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. At heavy load, its control mode changes to PWM mode automatically and it keeps high efficiency using synchronous rectifying technology. If only heavy load current operation is needed, PWM forced mode is available. In PWM forced mode, ripple noise is reduced. In shutdown mode, the current consumption is up to 1uA. 3.
