LP3906
August 28, 2009
Dual High-Current Step-Down DC/DC and Dual Linear
Regulator with I2C Compatible Interface
General Description
The LP3906 is a multi-function, programmable Power Man-
agement Unit, optimized for low power FPGAs, Microproces-
sors and DSPs. 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 ac-
cess to the internal control registers of the LP3906. The
LP3906 additionally features programmable power-on se-
quencing and is offered in a tiny 5 x 4 x 0.8mm LLP-24 pin
package.
