View Datasheet Manufacturer Site View Pricing & Stock

The MIC4690 SuperSwitcherâ„¢ is an easy-to-use, 500kHz step-down PWM voltage regulator. The MIC4690 achieves over 1A of continuous output current over a wide input voltage range in an 8-lead SO (small outline) package.

The high switching frequency of the MIC4690 allows the smallest surface-mount inductors and capacitors to be used. Internal compensation ensures fast transient response and a minimum amount of external components.

The MIC4690 features a power SO-8 package with a special lead frame that allows over 1A of continuous current. The MIC4690, housed in an SO-8, can replace larger TO-220 and TO-263 packages in many applications.

The MIC4690 allows for a high degree of safety. It has a wide input voltage range of 4V to 34V, allowing for it to be used in applications where input voltage transients may be present. Built-in safety features include over-current protection, frequency foldback protection, and thermal shutdown.

The MIC4690 is available in an 8-lead SO package with a junction temperature range of -40°C to +125°C.
