12 / 22 page SPM1006 Version 1.5 March 16, 2016 Page 12 of 22 Fig. 16 Start-Up Waveforms for SPM1006 (set to 1.8V output) without EN control Fig. 17 and Fig. 18 show the typical output voltage waveforms when SPM1006 is turned on and turned off by the EN pin. In these figures, the top trace is enable signal (EN), the middle trace is Power Good signal (PWRGD), and the bottom trace is the output voltage. Fig. 17 Enable Turn-On for SPM1006 (set to 1.8V, with IOUT = 6A) Fig. 18 Enable Turn-Off for SPM1006 (set to 1.8V, with IOUT = 6A) The startup and shutdown waveforms are similar for other output voltages. Pre-bias Startup Some applications require startup when there is a residual pre-bias voltage on the output. The SPM1006 can start in this condition and as long as the pre-bias voltage is lower than the final output the start-up waveform will be normal. Fig. 19 illustrates start up with pre-bias of approximately 50% of the nominal output voltage. Fig. 20 shows the start- up when the pre-bias is about 80% of the nominal output. |
