... The two modes of operation ensure that the MIC23250 maintains the highest efficiency throughout the entire load range. The MIC23250 operates from a 2.7V to 5.5V input and features internal power MOSFETs that can supply up to 400mA of output current on each channel. It can operate with a maximum duty cycle of 90% ...

... OUT ⎝ R BOTTOM Compensation The MIC23250 is designed to be stable with a 0.47µH to 4.7µH inductor with a minimum of 2.2µF ceramic (X5R) output capacitor. For the adjustable MIC23250, the total feedback resistance should be kept as high as possible to reduce current loss down the feedback resistor network. This helps to improve efficiency. A feed-forward ...

... HyperLight Load™ mode or PWM mode at a specific load current by selecting the appropriate inductance. For example in the graph below, when the inductance is 4.7µH the MIC23250 will transition into PWM mode at a load of approximately 4mA. Under the same condition, when the inductance is 1µH, the MIC23250 will transition into PWM mode at approximately 70mA. ⎞ ...
