... A logic high signal on the enable pin activates the output voltage of the device. A logic low signal on the enable pin deactivates the output and reduces supply current to 0.01µA. MIC23150 features built-in soft-start circuitry that reduces in-rush current and prevents the output voltage from overshooting at start up. Do not leave the EN pin floating ...

... DCR can represent a temperature rating significant efficiency loss. Refer to the Efficiency Considerations. Compensation The MIC23150 is designed to be stable with a 0.47µH to 2.2µH inductor with a minimum of 2.2µF ceramic (X5R) output capacitor. Duty Cycle The typical maximum duty cycle of the MIC23150 is 80%. ...

... As the load current increases, the MIC23150 goes into continuous conduction mode (CCM) and switches at a frequency centered at 4MHz. The equation to calculate the load when the MIC23150 goes into continuous conduction mode may be approximated by the following formula: As shown in the previous equation, the load at which MIC23150 transitions from HyperLight Load™ ...
