7.4.2 Shutdown Mode

The TPSM846C24 uses the EN pin to enable or disable power conversion. The EN pin must be pulled high to allow power conversion.

The EN pin provides electrical ON and OFF control for the TPSM846C24. When the EN pin voltage is below the EN low threshold, the device is in shutdown mode. In shutdown mode the stand-by current is 7.7 mA typically with VIN = 12 V. The TPSM846C24 also employs undervoltage lockout protection. If VIN is below the UVLO level, the output of the regulator is turned off.
