MIC2199

Minimum Pulsewidth

The MIC2199 has a specified minimum pulsewidth. This

minimum pulsewidth places a lower limit on the minimum duty

cycle of the buck converter.

Figure 5 shows the minimum output voltage versus input

supply voltage for the MIC2199. For example, for VIN = 15V,

VOUT = 1V would be the lowest achievable voltage that

conforms to the minimum-on-time.
