Beschreibung

PMP10655 is a dual-output synchronous buck converter reference design using the LM5140 controller IC. The reference design accepts an input voltage between 6Vin and 18Vin and is capable of supplying a maximum of 8A of continuous current (14A Peak) to the load, per output. Vout1 and Vout2 maintain regulation during cold-crank (Vin dip to 4.3Vin) and load-dump (Vin peak to 42Vin) conditions. Switching of the two converters are 180 degrees out of phase between each other. The design also features the LM5050-1 OR-ing controller configured for efficient reverse polarity protection of the input. PMP10655 is built on a 4-layer FR-4 PCB, with 2 oz. Copper on the Top and Bottom layers, and 1 oz. Copper on the two internal layers.

Eigenschaften

  • 2.2MHz switching to bypass AM band
  • Front-end high-efficiency reverse polarity protection
  • Smooth switching frequency foldback when in dropout
  • High-side and low-side gate drives with indepdendent rising and falling slew-rate control

Typische Anwendungen

  • Infotainment Systems
  • Automotive Electronics
  • Instrument Clusters / Advanced Driver Assistance (ADAS)
