Evaluation Kit for the MAX8663

Buy Now View Details

Features and Benefits

  • Two High-Efficiency 1MHz Synchronous Rectified Step-Down Regulators
  • Four LDO Regulators with Jumper-Selectable Output Voltages
  • Single-Cell Li+/Li-Polymer Charger
  • Smart Power Selector (SPS)
  • Power-OK, Charger Status, and Timeout Fault Indicators
  • 40-Pin, 5mm x 5mm x 0.8mm Thin QFN Package
  • Fully Assembled and Tested

Product Details

The MAX8663 evaluation kit (EV kit) is a fully assembled and tested circuit board that evaluates the MAX8663 power-management IC. The MAX8663 integrates two synchronous step-down regulators, four low-dropout linear regulators (LDOs), and a linear charger for a single-cell Li-ion (Li+)/Li-polymer battery. Maxim's Smart Power Selector™ (SPS) safely distributes power between an external power source (AC adapter, auto adapter, or USB source), battery, and the system load.

Applications

  • 3G Smart cellular phones
  • Other Handheld Devices
  • PDAs, portable media players (PMPs)
  • Portable GPS Navigation Devices (PNDs)

Product Details

The MAX8662 evaluation kit (EV kit) is a fully assembled and tested printed-circuit board (PCB) that evaluates the MAX8662 power-management IC. The MAX8662 integrates two synchronous rectified step-down regulators, a step-up regulator driving two to seven white LEDs (WLEDs), four low-dropout linear regulators (LDOs), and a linear charger for a single-cell Li-ion (Li+) battery. Maxim's Smart Power Selector™ (SPS) safely distributes power between an external power source (AC adapter, auto adapter, or USB source), battery, and the system load.

Applications

  • 3G Smart cellular phones
  • Other Handheld Devices
  • PDAs, portable media players (PMPs)
  • Portable GPS Navigation Devices (PNDs)
