Figure 32. TPA2013D1 in Stereo With the TPA2032D1
Use the boost converter of the TPA2013D1 as a power supply for the flash LED of a digital still camera. Use a
microprocessor or other device or synchronize the flash to shutter sound that typically comes from the speaker of
a digital still camera. Figure 33 shows a typical circuit for this application. LEDs, switches, and other components
will vary by application.
