A step-by-step flowchart of what happens when the power button is pressed. Power On Sequence (Step-by-Step)
Check if the IC is receiving its main VIN power input. Next, verify the EN (Enable) signal coming from the EC or a resistor divider network. If the IC has input power and enable signals but no output, check the resistance to ground on the output inductors to rule out a short-circuit before replacing the regulator IC.
