MAX17543ATP+ Related Parts

MAX17543ATP+ Frequently Asked Questions (FAQ)

  • A good PCB layout for the MAX17543ATP+ involves keeping the input and output capacitors close to the device, using a solid ground plane, and minimizing trace lengths and widths to reduce parasitic inductance and capacitance. A 4-layer PCB with a dedicated power plane and a solid ground plane is recommended.

  • The input capacitor should be a low-ESR ceramic capacitor with a value between 1uF to 10uF, while the output capacitor should be a low-ESR ceramic or tantalum capacitor with a value between 10uF to 22uF. The capacitor selection should be based on the specific application requirements, such as output voltage ripple and transient response.

  • The MAX17543ATP+ has an operating ambient temperature range of -40°C to +125°C, but the maximum junction temperature should not exceed 150°C. The device should be derated for temperatures above 85°C to ensure reliable operation.

  • The MAX17543ATP+ has a built-in OVP and UVLO feature. The OVP threshold is set to 12.6V, and the UVLO threshold is set to 4.2V. The device will shut down if the input voltage exceeds the OVP threshold or falls below the UVLO threshold.

  • The MAX17543ATP+ has a maximum input voltage range of 4.5V to 12.6V. The device can operate from a single lithium-ion battery or from a 5V or 12V power supply.
