Example requirements for a typical 5-V application. The input voltages are here for illustration purposes only. See Section 7.6 for minimum operating input voltage. The minimum input voltage necessary to achieve proper output regulation depends on the components used. See Figure 9-10 for typical drop-out behavior.
|DESIGN PARAMETER||EXAMPLE VALUE|
|Input voltage range||8 V to 18 V steady-state, 5.5 V to 36 V transients|
|Output current||0 A to 5.5 A|
|Switching Frequency at 0-A load||Critical: must have > 250 kHz|
|Current Consumption at 0-A load||Not critical: < 100 mA acceptable|
|Synchronization||Yes: 300 kHz supplied by MCU|
