LP8720中文资料一个降压直流/直流转换器和五个线性稳压器，具有 I2C 兼容接口数据手册TI规格书

描述 Description

The LP8720 is a multi-function, programmable Power Management Unit, optimized for sub block power requirement solution. This device integrates one highly efficient 400 mA step-down DC-DC converter with Dynamic Voltage Scale (DVS), five low noise low dropout (LDO) voltage regulators and a 400 KHz I2C-compatible interface to allow a host controller access to the internal control registers of the LP8720. The LP8720 additionally features programmable power-on sequencing. LDO regulators provide high PSRR and low noise ideally suited for supplying power to both analog and digital loads. The package will be the smallest 2.5 mm x 2.0 mm DSBGA 20-bump package.

特性 Features

• 5 Low Noise LDO’s for up to 300 mA
• High Efficiency PFM Mode @Low IOUT
• Low Inductance 2.2 µH @ 2 MHz Clock
• I2C-Compatible Interface for the Controlling of Internal Registers
• Programmable Vout from 0.8V to 2.3V on DC-DC
• 200 mV Typ Dropout Voltage at 300 mA on LDO’s
• 2% (Typ) Output Voltage Accuracy on LDO’s
