Beschreibung
PMP20682 is a synchronous buck converter reference design utilizing the LM5141-Q1 synchronous buck controller I.C. The design accepts an input voltage of 5V to 40V and provides a 3.3V output capable of supplying 10A of current to the load. An EMI filter is incorporated on the input. Optional frequency dithering and slew rate control are available for additional EMI control. Mounting holes are provided for a bottom-side MOSFET heat sink.
Eigenschaften
- Peak current-mode control
- Selectable frequency dithering
- Input EMI filter
- Wide input voltage range
- Selectable diode emulation or forced PWM
Typische Anwendungen
- Hybrid Cluster with Active Graphics Support / Hybrid Cluster with Informational Graphics Support
