Figure 3-1, Figure 3-2, and Figure 3-3 show the waveform of Vout, SW1, SW2, and ITEC when Vout <
Vin. The maximum voltage applied to the TEC element is about +10 V and ITEC is
tested up to 4.34 A. Figure 3-4, Figure 3-5, and Figure 3-6 show the waveforms of LM5176 when Vout > Vin. In contrast to
above, the maximum voltage is approximately -10 V and ITEC is up to -4.42 A.
