MIC4690YM More Semiconductors - ICs by Microchip Technology
500KHz 1A SuperSwitcher™ Buck Regulator
| Status: | Active |
|---|---|
| Series: | MIC4690 |
| RoHS: | Compliant |
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.
