Aaustriamicrosystems公司的 AS3606/07是高档电源管理解决方案,包括了电池供电的移动设备所需要的IC和外设,集成了3个DC/DC转换器和5个低噪音LDO,单电源电压2.7V-5.5V工作,升压转换器高达30V,可用于OLED电源和白光LED背景光电源. AS3606/07还包括了锂离子电池充电器,最大充电电流1A.主要用于PMP,手提导航设备(PND),电子图书,平板PC等.本文介绍了AS3606/07主要特性, 方框图, LDO 方框图, DC/DC转换器方框图, 充电器方框图以及AS3606和AS3607的应用电路.

The device offers advanced power management functions. All necessary ICs and peripherals in a battery powered mobile device are supplied by the AS3606/07. It features 3 DCDC converters as well as 5 low noise LDOs. The different regulated supply voltages
are programmable via the serial control interface.

The step-up converter for the backlight can operate up to 30V. Both constant voltage (OLED supply) as well as constant current (white LED backlight) operations with 2 current sinks are possible. An internal voltage protection is limiting the output voltage in the case of external component failures.
