A good PCB layout for the MAX1655ESE+ involves keeping the input and output traces short and wide, using a solid ground plane, and placing the input and output 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 power-up and power-down of the MAX1655ESE+, it's recommended to follow a power-up sequence where the input voltage (VIN) is applied before the enable pin (EN) is asserted. During power-down, the EN pin should be de-asserted before removing the input voltage.
The MAX1655ESE+ can handle input voltages up to 28V, but it's recommended to operate within the specified input voltage range of 4.5V to 24V for optimal performance and reliability.
The output voltage of the MAX1655ESE+ can be calculated using the formula: VOUT = (VIN x R1) / (R1 + R2), where R1 and R2 are the resistors used in the feedback network.
The MAX1655ESE+ can deliver up to 1.5A of output current, but it's recommended to operate within the specified output current range of 0A to 1.2A for optimal performance and reliability.
