LMR62421XSDDEMO/NOPB Datasheet PDF - TI

The LMR62421XSDDEMO/NOPB is a demo board for LMR62421, a high frequency switching boost regulator which offers small size and high power conversion efficiency. The part operates at a 1.6MHz switching frequency. It provides all the active functions to provide local DC to DC conversion with fast transient response and accurate regulation in the smallest PCB area capable of supplying up to 2.1A of switch current. The LMR62421 is internally compensated, so it is simple to use and requires few external components. The LMR62421 uses current mode control to regulate the output voltage in a range from 3V to 24V. Additional features include internal soft start which helps reduce inrush current and thermal shutdown.
