Product Overview

The LMR24220RB/NOPB is a LMR24220 multi rail reference board, implements an extremely compact solution. It is designed to convert from 12V or 24V rails down to typical point of load voltages of 3.3V, 1.8V and 1.2V. This design utilizes an LMR24220 nano regulator and two LMZ10501 nano modules to demonstrate a complete solution for space constrained multi rail applications. The LMR24220 nano regulator is ideal for intermediate rail conversions and can withstand input voltages up to 42V. It uses a constant on time (COT) with emulated ripple mode architecture that requires no loop compensation and allows the use of low ESR ceramic capacitors. To further reduce conducted noise on the input supply a pi filter has been implemented on the LMR24220. The LMZ10501 nano module is ideal at the point of load and uses a current mode architecture combined with an integrated inductor for high efficiency, low noise and low EMI.
  • 5V to 32V input voltage range
  • 3.3V/1.8V /1.2V output voltage rails
  • Up to 1000mA output current per rail
  • Small solution size (20.32mm x 13.34mm x 2mm)
  • No external compensation require
