7脚EN
The COMP/EN is an multifunctional pin: control loop
compensation and chip enable as shown in Figure 1. An
Enable Comparator monitors the COMP/EN pin voltage for
chip enable. A signal level transistor is adequate to pull
this pin down to ground and shut down the uP6101. A 80uA
current source charges the external compensation network
with 0.45V ceiling when this pin is released. If the voltage
at COMP/EN pin exceeds 0.3V, the uP6101 initiates its
softstart cycle.
