Functional Description
Synchronous Buck Converter
The EN2340QI is a highly integrated synchronous,
buck converter with integrated controller, power
MOSFET switches and integrated inductor. The
nominal input voltage (PVIN) range is 4.5V to 14V
and can support up to 4A of continuous output
current. The output voltage is programmed using
an external resistor divider network. The control
loop utilizes a Type IV Voltage-Mode compensation
network and maximizes on a low-noise PWM
topology. Much of the compensation circuitry is
internal to the device. However, a phase lead
capacitor is required along with the output voltage
feedback resistor divider to complete the Type IV
compensation
