MAXIM INTEGRATED PRODUCTS  MAX8660ETL+T  芯片, 电源管理

The is a high efficiency, low IQ, power management IC PMIC with dynamic voltage management for mobile applications in 40 pin TQFN package. Four synchronous step-down DC to DC outputs REG1, REG2, REG3, REG4, three linear regulators REG5, REG6, REG7, REG8 and an 8th always on LDO are integrated with power management functions. Two dynamically controlled DC to DC outputs power the processor core and internal memory. Two other DC to DC converters power I/O, memory and other peripherals. Additional functions include on/off control for outputs, low battery detection, reset output and 2-wire I2C serial interface. All step-down DC to DC outputs use fast 2MHz PWM switching and tiny external components. It automatically switches from PWM to high efficiency, light load operation to reduce operating current and extend battery life. A forced PWM option allows low noise operation at all loads. Overvoltage lockout protects device against inputs up to 7.5V.
