Controlling Output Ripple & Achieving ESR Independence in Constant On-Time (COT) Regulator Designs (Rev. A)
Texas InstrumentsOf all the voltage regulator control strategies ever devised, the hysteretic regulator is probably about the simplest. This control methodology simply turns a switch on when the output voltage is below a reference and turns the switch off when the output rises to a slightly higher reference. The output ripple is therefore a direct function of the difference between the upper and lower reference threshold, the hysteresis amplitude. It’s hard to imagine something much simpler and, as usual, with simplicity comes performance shortcomings.
Optimizing OMAP3630 BOOT Sequence Using the TPS65023-Q1 (Rev. A)
Texas InstrumentsThe TPS65023-Q1 multi-rail power-supply integrated circuit (IC) realizes all necessary features to supply the OMAP3630 processor. The TPS65023-Q1 device is an integrated power-management IC (PMIC). The device is suited for applications powered by one Li-Ion or Li-Polymer cell requiring multiple power rails. The TPS65023-Q1 device provides three highly-efficient 1500-mA step-down DC-DC converters
