Texas Instruments LMR24220RB/NOPB Multi-Rail Reference Board

Texas Instruments LMR24220RB/NOPB 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.
