HIGH PERFORMANCE DUAL CHANNEL CURRENT MODE CONTROLLERS

Instructions for Use:

1. Input Voltage (VIN):

   • Ensure the input voltage is within the range of 2.7V to 40V.
   • The input voltage should be stable and free from excessive ripple or noise.

2. Output Voltage (VOUT):

   • The output voltage can be adjusted between 5V and 15V.
   • Use the external feedback resistor network to set the desired output voltage.

3. Output Current (IOUT):

   • The device can provide a continuous output current up to 3A, with a typical value of 1.5A.
   • Ensure proper heat dissipation if operating at high currents.

4. Switching Frequency (fSW):

   • The switching frequency is adjustable between 100kHz and 500kHz.
   • Set the frequency using an external resistor connected to the RT/CT pin.

5. Quiescent Current (IQ):

   • The quiescent current is typically 2.5mA and can go up to 5mA under certain conditions.
   • This current is drawn even when there is no load on the output.

6. Dropout Voltage (VDROPOUT):

   • The dropout voltage is the difference between the input and output voltages when the output is under load.
   • It is typically 1.2V and can go up to 2.5V at 1A output current.

7. Efficiency (η):

   • The efficiency of the converter is typically 85% when operating at 12V input, 5V output, and 1A output current.
   • Efficiency can vary based on input voltage, output voltage, and load conditions.

8. Operating Temperature (Toperating):

   • The device can operate within the temperature range of -40°C to 125°C.
   • Ensure adequate cooling if operating in high-temperature environments.

9. Storage Temperature (Tstorage):

   • The device can be stored in temperatures ranging from -65°C to 150°C.
   • Avoid exposing the device to extreme temperatures for extended periods.

Additional Notes:

• Always use appropriate decoupling capacitors on both the input and output sides to ensure stability and reduce noise.
• Refer to the datasheet for detailed information on external component selection and layout guidelines.
