Overview

  • Two 95%-Efficient 1MHz Buck Regulators
    • Main Regulator: 0.98V to VIN at 1200mA
    • Core Regulator: 0.98V to VIN at 900mA
  • 1MHz Boost WLED Driver
    • Drives Up to 7 White LEDs at 30mA (max)
    • PWM and Analog Dimming Control
  • Four Low-Dropout Linear Regulators
    • 1.7V to 5.5V Input Range
    • 15µA Quiescent Current
  • Single-Cell Li+ Charger
    • Adapter or USB Input
    • Thermal-Overload Protection
  • Smart Power Selector (SPS)
    • AC Adapter/USB or Battery Source
    • Charger-Current and System-Load Sharing

The MAX8662/MAX8663 power-management ICs (PMICs) are efficient, compact devices suitable for smart cellular phones, PDAs, Internet appliances, and other portable devices. They integrate two synchronous buck regulators, a boost regulator driving two to seven white LEDs, 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. When system load peaks exceed the external source capability, the battery supplies supplemental current. When system load requirements are small, residual power from the external power source charges the battery. A thermal-limiting circuit limits battery-charge rate and external power-source current to prevent overheating. The PMIC also allows the system to operate with no battery or a discharged battery.

The MAX8662 is available in a 6mm x 6mm, 48-pin TQFN package, while the MAX8663, without the LED driver, is available in a 5mm x 5mm, 40-pin TQFN package.

Applications

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