Средства разработки интегральных схем (ИС) управления питанием LMR62421XSDDEMO/NOPB

Демонстрационная плата для ВЧ импульсного стабилизатора , компактный, частота коммутации 1.6МГц

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.

• 2.7V to 5.5V input voltage range
• 12V output voltage (default setting)
• 500mA output current from 3.5V input supply
• 300mA output current from 2.7V input supply
• Switching frequency of 1.6MHz
• Low component count
• Small solution size 27.5mm x 36.9mm
• Extremely easy to use
• Tiny overall solution reduces system cost
