A good PCB layout for the MAX4626EUK+T involves keeping the input and output traces short and separate, using a solid ground plane, and placing the device close to the power source. Additionally, using a shielded inductor and placing it away from sensitive analog circuits can help reduce EMI.
To ensure the MAX4626EUK+T operates within its recommended operating conditions, verify that the input voltage is within the specified range (4.5V to 5.5V), the output current is within the specified range (up to 1A), and the ambient temperature is within the specified range (-40°C to +85°C).
The recommended input capacitor value for the MAX4626EUK+T is 10uF to 22uF, with a voltage rating of 6.3V or higher. A low-ESR ceramic capacitor, such as an X5R or X7R type, is recommended.
The output voltage of the MAX4626EUK+T can be calculated using the formula: VOUT = (R1/R2) * (1.25V), where R1 and R2 are the resistors connected to the FB pin. The output voltage range is 0.8V to 5.5V.
The maximum allowable ripple current for the MAX4626EUK+T is 30% of the maximum output current (1A). This means the ripple current should be limited to 300mA or less.
