3.1.1.1.2.3 Power Supply 15-V/0.5-A

This is another compact power module based on SN6501-Q1 and TL1963A-Q1. The design is based off Signal and power isolation with 3.3 V / 5 V input and 12 V / 15 V output. Design information is available in this user guide. The layout of this module is customized to fit the requirements of this EV traction reference design and is shown in Figure 3-14.
