LP3906  
Dual High-Current Step-Down DC/DC and Dual Linear  
Regulator with I2C Compatible Interface  
General Description  
Features  
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.  
Compatible with advanced applications processors and
