8.2.3 Application Performance Curves

Unless otherwise specified, VIN = 12 V, VOUT = 3.3 V, FS = 500 kHz and room temperature. See Application Performance

Curves for bill of materials for each VOUT and FS combination.

VOUT = 3.3 V

FS = 500 kHz

Figure 39. BOM for VOUT = 3.3 V FS = 500 kHz

VOUT = 3.3 V

FS = 500 kHz
