Enpirion® Power Datasheet  
EC7100VQI PWM DC/DC Controller with  
VS Inputs for FPGA Power Regulator  
DS-1043  
Datasheet  
The Altera® Enpirion® EC7100VQI is a Single-Phase  
Features  
Synchronous-Buck PWM controller. The wide 3.3V to 25V input  
voltage range is ideal for systems that run on battery or AC-  
adapter power sources. The EC7100VQI is a low-cost solution for  
applications requiring dynamically selected slew-rate controlled  
output voltages. The soft-start and dynamic setpoint slew-rates are  
capacitor programmed. Voltage identification logic-inputs select  
four resistor-programmed setpoint reference voltages that directly  
set the output voltage of the converter between 0.5V and 1.5V, and  
up to 5V with a feedback voltage divider.

Extremely Flexible Output Voltage Programmability  
The EC7100VQI modulator has equivalent light-load efficiency,  
faster transient performance, accurately regulated frequency  
control and all internal compensation. These updates, together  
with integrated MOSFET drivers and schottky bootstrap diode,  
allow for a high-performance regulator that is highly compact and  
needs few external components. The EC7100VQI has differential  
remote sensing for output voltage and selectable switching  
frequency. For maximum efficiency, the converter automatically  
enters diode-emulation mode (DEM) during light-load conditions  
such as system standby.
