The recommended layout and placement for the MAX6190AESA+ involves keeping the input and output capacitors close to the device, using a solid ground plane, and minimizing the length of the input and output traces. A 4-layer PCB with a dedicated ground plane is recommended.
To ensure stability, ensure that the output capacitor is within the recommended range (10uF to 100uF), the input capacitor is at least 1uF, and the feedback resistors are within the recommended range (1kΩ to 10kΩ). Also, avoid using ceramic capacitors with high ESR.
The MAX6190AESA+ can handle input voltages up to 42V, but it's recommended to keep the input voltage below 36V to ensure reliable operation.
The output voltage of the MAX6190AESA+ can be calculated using the formula: VOUT = VREF x (1 + R1/R2), where VREF is the internal reference voltage (1.25V), R1 is the feedback resistor, and R2 is the divider resistor.
The MAX6190AESA+ can deliver up to 1A of output current, but it's recommended to keep the output current below 500mA to ensure reliable operation and minimize heat generation.
