(1) External components such as the diode, inductor, input and output capacitors can affect switching regulator performance. When the
LM2586 is used as shown in Figure 20 and Figure 21, system performance will be as specified by the system parameters.
(2) All room temperature limits are 100% production tested, and all limits at temperature extremes are specified via correlation using
standard Statistical Quality Control (SQC) methods.
(3) A 1.0 MΩ resistor is connected to the compensation pin (which is the error amplifier output) to ensure accuracy in measuring A
VOL
