7.2.1.1 Design Requirements

For this design example, use the following as the input parameters:

Table 7-1 Design Requirements
DESIGN PARAMETER(1)EXAMPLE VALUE
Input voltage range14.5 V to 36 V
Output voltage12 V
Input ripple voltage300 mV
Output ripple voltage50 mV
Output current rating1 A
Operating frequency500 kHz
(1) As an additional constraint, the design is set up to be small size and low component height.
