This reference design is intended for users designing with the TMS320C2834x microcontrollers. This design, employing sequenced power supplies, describes a system with an input voltage of 12 V and uses high-efficiency DC/DC converters with integrated FETs for a simple, small design. - TPS6211X Driving EN and SYNC pinPDF, 70 Kb, File published: Jan 15, 2008
The TPS6211x high-input-voltage buck converters operate over a wide, input-voltage range. The control and input signal can also be controlled from 1.8-V logic levels up to maximum input voltage.One characteristic of the EN and SYNC control circuits is the increase in leakage current when these pins are driven by a voltage level less than 4 V.In this application report, the difference in th - Power for TMS320C5504/05 (Rev.
