RT7277GSP Frequently Asked Questions (FAQ)
-
A 4-layer PCB with a solid ground plane and thermal vias is recommended. The RT7277GSP's thermal pad should be connected to the ground plane to improve heat dissipation.
-
To ensure stable output voltage regulation, it is recommended to use a minimum output capacitance of 10uF with an ESR of 1ohm or less, and to decouple the input with a 10uF capacitor.
-
The maximum input voltage that can be applied to the RT7277GSP is 28V, but it is recommended to operate within the specified input voltage range of 7V to 25V for optimal performance and reliability.
-
The RT7277GSP has a built-in overcurrent protection (OCP) feature that limits the output current to 2.5A. Additionally, it is recommended to add external overcurrent protection using a fuse or a current sense resistor to prevent damage from excessive current.
-
The recommended startup sequence is to first apply the input voltage, followed by the enable signal (EN). This ensures that the internal voltage regulators are properly initialized before the output voltage is enabled.
