Maxim MAX8660高效低IQ动态电压管理方案

Maxim 公司的MAX8660/MAX8661是应用处理器的功率管理集成电路（PMIC），特别适用于智能手机，PDA，互联网设备以及其它手提设备。器件具有四个降压DC/DC转换器输出，三个线性稳压器，以及第八个常开的LDO。两个动态控制的DC/DC输出给处理器内核和内部存储器供电。本文介绍了MAX8660/MAX8661 主要特性，功能方框图，和Marvell PXA3xx处理器连接框图以及典型应用框图，MAX8660评估板主要特性，电路图和材料清单（BOM）。

The MAX8660/MAX8661 power management ICs (PMICs) power applications processors (APs) in smart cellular phones, PDAs, Internet appliances, and other portable devices.

Four step-down DC-DC outputs, three linear regulators, and an 8th always-on LDO are integrated with powermanagement functions. Two dynamically controlled DCDC outputs power the processor core and internal memory.

Two other DC-DC converters power I/O, memory, and other peripherals. Additional functions include on/off control for outputs, low-battery detection, reset output, and a 2-wire I2C serial interface. The MAX8661 functions the same as the MAX8660, except it lacks the REG1 step-down regulator and the REG7 linear regulator.
