MIC94300YMT EV: 1.8 ~ 3.6 Vin, 200mA Load Switch

Summary

The MIC94300 is an integrated load switch that incorporates Micrel’s Ripple Blocker™ active filter technology. The MIC94300 provides high frequency ripple attenuation for applications where switching noise cannot be tolerated by sensitive downstream circuits such as RF Applications. The MIC94300 replaces a high-side switch, large filtering inductor, and capacitors to save board area.

The MIC94300 operates from an input voltage of 1.8 V to 3.6 V, allowing true load switching of low-voltage power rails in any electronic device. The output voltage is set at a fixed drop from the input voltage.

The MIC94300 evaluation board requires an input power supply that is capable of delivering a minimum of 300 mA at a voltage of 1.8 V to 3.6 V. The output load can be either active or passive.

The MIC94300 evaluation board does not have reverse polarity protection. Applying a negative voltage to the Vin terminal may damage the device.
