Product Details

The MAX8815A evaluation kit (EV kit) is a fully assembled and tested printed-circuit board (PCB) for evaluating the MAX8815A step-up converter. The MAX8815A is a 1A (maximum load), 97% efficient, 35µA quiescent current step-up converter with True Shutdown™ and is ideal for use in DSC, DVC, and other handheld applications. The MAX8815A EV kit is designed for a 5V output and also provides a jumper for evaluation of fixed-frequency pulse-width-modulation mode (FPWM) or normal mode.

Applications

  • Cell Phones, PDAs, MP3 Players
  • DSC and DVC
  • Microprocessor/DSP Core Power
  • PCMCIA Cards
  • Portable Handheld Devices
