EN2340QI Typical application Circuitry

EN2340QI

The EN2340QI is a high-performance synchronous buck regulator, designed to provide efficient and accurate voltage regulation. Manufactured by Intel (previously Altera), this chip is designed to work with a wide range of input voltages and produce a stable output voltage. Here is a detailed guide to circuit connections for the EN2340QI regulator:

1. Input Voltage: Connect the input voltage source to the VIN pin. The EN2340QI accepts a wide range of input voltages from 2.375V to 5.5V. To improve stability, it is advisable to connect a decoupling capacitor (typically 10uF) close to the VIN pin and ground.

2. Ground Connections: Connect all the GND pins of the EN2340QI to the system ground. Proper grounding is crucial for stable operation and noise reduction.

3. Output Voltage: The VOUT pin provides the regulated output voltage. Connect a bulk capacitor (usually in the range of 150uF to 220uF) and a smaller ceramic capacitor (typically 10uF) to the VOUT pin and ground to ensure stability and minimize output voltage ripple.

4. Feedback: The FB pin is used as feedback to adjust the output voltage. Connect a resistor divider network from the VOUT pin to the FB pin and ground. The resistor values may be estimated using the formula provided in the EN2340QI datasheet.

5. Enable Pin: The EN pin enables or disables the regulator. Connect the EN pin to a digital control signal or a logic-high voltage (typically the same as VIN) to enable the regulator. Alternatively, connect it to ground to disable the regulator.

6. Power Good Indicator: The PGOOD pin serves as a power-good indicator. Connect a pull-up resistor from the PGOOD pin to the input voltage. When the output voltage is within the specified regulation range, the PGOOD pin is pulled low; otherwise, it is pulled high.

7. Soft Start: The SS/TR pin controls the soft-start ramp-up time of the output voltage. Connect a capacitor from the SS/TR pin to ground to adjust the soft-start time.

8. Frequency Synchronization: To synchronize the switching frequency with an external clock, utilize the SYNC pin. If frequency synchronization is needed, connect the SYNC pin to an external clock source.

9. Compensation: The COMP pin is used to stabilize the control loop. From the COMP pin to ground, connect a series RC network followed by a capacitor. Refer to the EN2340QI datasheet for recommended component values.

10. Switching Frequency: The EN2340QI has a programmable switching frequency. Connect the RT pin to ground through a resistor to set the desired switching frequency.

Please consult the EN2340QI datasheet for comprehensive information on pin assignments, electrical specifications, and component value recommendations. Proper circuit connections are essential for achieving optimal performance and reliable operation with the EN2340QI regulator.
