9 / 17 page IL2575-xx Figure 16. Inverting Buck–Boost Regulator with Delayed Startup It has been already mentioned above, that in some situations, the delayed startup or the undervoltage lockout features could be very useful. A delayed startup circuit applied to a buck–boost converter is shown in Figure 16. Figure 22 in the “Undervoltage Lockout” section describes an undervoltage lockout feature for the same converter topology. NOTE: This picture does not show the complete circuit. Figure 17. Inverting Buck–Boost Regulator Shut Down Circuit Using an Optocoupler With the inverting configuration, the use of the ON/OFF pin requires some level shifting techniques. This is caused by the fact, that the ground pin of the converter IC is no longer at ground. Now, the ON/OFF pin threshold voltage (1.4 V approximately) has to be related to the negative output voltage level. There are many different possible shut down methods, two of them are shown in Figures 17 and 18. Rev. 00 |
