Product Summary

The lp8720tlx-b is a multi-function, programmable Power Man- agement 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 lp8720tlx-b. The lp8720tlx-b additionally features programmable power-on sequencing. The applications of the device are Cellular Handsets and Portable hand-held products.
