... PFM threshold. Thereafter the converter continues operation in PFM mode. 4.3 Shutdown Mode Connecting ENABLE to GND places the TLE6389GV, TLE6389G33 and TLE6389G50 in shutdown mode. In shutdown, the reference, control circuitry, external switching MOSFET, and the oscillator are turn off and the output falls to 0V. Connect ENABLE to IN for normal operation ...
