LP3907  
Dual High-Current Step-Down DC/DC and Dual Linear  
Regulator with I2C Compatible Interface  
General Description  
Features  
The LP3907 is a multi-function, programmable Power Man-  
agement Unit, optimized for low power FPGAs, microproces-  
sors and DSPs. This device integrates two highly efficient 1A/  
600mA 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 LP3907. The  
LP3907 additionally features programmable power-on se-  
quencing and a tiny 4 x 4 x 0.8mm 24–pin LLP pin package.  
Compatible with advanced applications processors and  
FPGAs  
2 LDOs for powering Internal processor functions and I/Os  
High speed serial interface for independent control of  
device functions and settings  
Precision internal reference  
Thermal overload protection  
Current overload protection  
24-lead 4 × 4 × 0.8mm LLP package  
Key Specifications  
Software Programmable Regulators  
External Power-on-reset function for Buck1 and Buck2  
(i.e., Power Good with delay function)  
Step-Down DC/DC Converter (Buck)  
1A/600mA output current  
Undervoltage lock out detector to monitor input supply  
voltage  
Programmable VOUT from:
