2. Description

The LXDC3EP series is a 1A output step-down DC-DC converter, which is suitable for a space-limited or

noise-sensitive application. The device utilizes an inductor-embedded ferrite substrate, and the substrate

eliminates radiated EMI noise and conduction noise efficiently.

With just this device, it can be used as a LDO replacement Its low noise feature assures reliable power supply

replacement.

quality.

The LXDC3EP series has a mode pin that allows the user to select Forced PWM mode or Power

Power-Save mode that

changes modes between pulse-skip operation and PWM operation automatically depending on the load.

conditions,

battery life. When Forced PWM mode is selected, it works at a fixed frequency (4MHz) within the load range. The

advantages of this mode are easy filtering of the switching frequency and a better load transient response.

The integrated over current protection and the thermal shutdown protection features offer reliable power supply

operation.
