MIC4690YM by Microchip Technology

500KHz Simple Buck Regulator
Features
SO-8 package with over 1A output current
Fixed 500kHz operation
Wide 4V to 34Vinput voltage range
Output voltage adjustable to 1.23V
All surface mount solution
Internally compensated with fast transient response
Up to 85% efficiency
Overcurrent protection
Frequency foldback short-circuit protection
Thermal shutdown
Description
The MIC4690 SuperSwitcher™ 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.
