DESCRIPTION (CONTINUED)
This device integrates two highly efficient 1.5A Step-Down DC/DC converters with dynamic voltage management
(DVM), two 300mA Linear Regulators and a 400kHz I²C compatible interface to allow a host controller access to
the internal control registers of the LP3906. The LP3906 additionally features programmable power-on
sequencing and is offered in a tiny 5 x 4 x 0.8mm WQFN-24 pin package.
