The recommended PCB layout for the MAX1739EEP involves keeping the input and output capacitors close to the device, using a solid ground plane, and minimizing the length of the traces between the device and the capacitors. Additionally, it is recommended to use a separate power plane for the input voltage and to avoid routing high-frequency signals near the device.
The selection of input and output capacitors for the MAX1739EEP depends on the specific application requirements. In general, low-ESR capacitors with a high ripple current rating are recommended. The input capacitor should be able to handle the input voltage and current, while the output capacitor should be able to handle the output voltage and current. A minimum capacitance of 10uF is recommended for both input and output capacitors.
The MAX1739EEP is rated for operation over a temperature range of -40°C to +85°C. However, the device can be operated at temperatures above +85°C with derating. It is recommended to consult the datasheet for specific derating information.
The MAX1739EEP has a built-in overvoltage protection (OVP) feature that can be enabled by connecting the OVP pin to a voltage source. The OVP threshold can be set by selecting the appropriate resistor value. Additionally, external overvoltage protection circuits can be implemented using zener diodes or voltage supervisors.
The recommended input voltage range for the MAX1739EEP is 2.5V to 5.5V. However, the device can operate with input voltages as low as 2.2V and as high as 6V, but with reduced performance and efficiency.
