A good PCB layout for the ECMF02-3F3 involves keeping the input and output traces as short as possible, using a solid ground plane, and placing the decoupling capacitors close to the device. Additionally, it's recommended to use a 4-layer PCB with a dedicated power plane and a dedicated ground plane.
To ensure proper decoupling, place a 10uF ceramic capacitor between the VIN pin and the GND pin, and a 100nF ceramic capacitor between the VOUT pin and the GND pin. These capacitors should be placed as close to the device as possible.
The ECMF02-3F3 can handle input voltages up to 36V, but it's recommended to keep the input voltage below 30V for optimal performance and reliability.
The output voltage of the ECMF02-3F3 can be adjusted by connecting a resistor divider network between the VOUT pin and the GND pin. The output voltage can be calculated using the formula: VOUT = 1.25V x (1 + R1/R2), where R1 and R2 are the resistors in the divider network.
The ECMF02-3F3 can provide a maximum output current of 3A, but it's recommended to keep the output current below 2.5A for optimal performance and reliability.
