Description
MIC4690YM-TR MICREL Diode Zener Single 3.3V 6% 500mW Automotive 2-Pin DO-35 T/R RoHS
MIC4690 Series 34 V 500 kHz 1 A SuperSwitcher™ Buck Regulator – SOIC-8
The MIC4690YM TR SuperSwitcher™ is an easy-to-use, 500 kHz step-down PWM voltage regulator. The MIC4690 achieves over 1 A 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.
