TPS61178: Without Load Disconnect Function, EN=H,Output=16V,EN=L,Output=0V?

Part Number: TPS61178

Hi,

I use TPS61178 without load Disconnect function, But I hope the EN signal can control the ouput voltage. Described as follows:

If EN=H(3.3V), Output=16V,

If EN=L(0V), Output=0V,  Right ?

    Dear sir:
    When the input voltage is above UVLO rising threshold of 2.7 V and the EN pin is pulled high above 1.2 V, the TPS61178X is enabled. When the EN pin is pulled below 0.4 V, the TPS61178x goes into the shutdown mode and stops switching.

    So you should design the Vout target as 16V.
    And if disable the converter, the converter will stop the switch.
