Description

The TIDA-00808 is a simple DC/DC inverting power supply reference design for industrial applications. It takes a wide input voltage between 4.5V and 55V and generates a negative 5V @ 1.75A output with 86% peak efficiency. Since this design is inverting, the maximum output current increases as the input voltage increases. The reference design features the LMZ36002 SIMPLE SWITCHER DC/DC step down power module for compact solution size and simplicity. The board dimension is 76.2 x 76.2 mm (3 x 3 inch) with the solution size of only 30.607 x 20.828 mm (1.205 x 0.82 inch).

Features
  • Input: 4.5V to 55V
  • Output: -5V @ 1.75A
  • Peak efficiency 86%
  • Simple design that features integrated shielded inductor and requires minimum external components
  • Compact solution size, < 637.5 mm2     
  • Tested DC/DC switching power supply sub-circuit
