TWL6030数据手册集成电路（IC）的电源管理-专用规格书PDF

描述 Description

The TWL6030 device is an integrated power-management integrated circuit (IC) for applications powered by a rechargeable battery. The device provides seven configurable step-down converters with up to 2.0-A capability for memory, processor core, I/O, auxiliary, preregulation for LDOs, and so forth. The device also contains 11 LDO regulators that can be supplied from a battery or a preregulated supply. The power-up and power-down controller is configurable and can support any power-up and power-down sequences (programmed in OTP memory). The real-time clock (RTC) provides a 32-kHz output buffer, second, minute, hour, day, month, year information, and alarm wake up. The TWL6030 device supports 32-kHz clock generation based on a crystal oscillator. The device integrates a switched-mode charger allowing faster battery charge, higher efficiency, and less power dissipation.
The TWL6030 device generates power supplies for OMAP™ 4 processors and operates together with the TWL6040 device, which includes all audio and related detection features. For audio IC parameters, see the TWL6040 data sheet. The TWL6030 device is available in an nFBGA package, 7.0 mm x 7.0 mm, with a 0.4-mm ball pitch.
