Altera EC7100VQI

控制器，FPGA3.3V ~ 25V0.5V ~ 5V

Overview

Enpirion's EC7100VQI Single-Phase Synchronous-Buck PWM Controller has a wide 3.3V to 25V input voltage range and 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. 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.
