Analog current limit adjustment for linear and switching regulators |
摘要 |
Circuits and methods for dynamic adjustment of the current limit of a power management unit to avoid unwanted automatic interruption of the power flow have been disclosed. The invention can be applied to switched and linear DC-to-DC converters. The power management unit is automatically adjusted to the output resistance of a power source (including interconnect resistance). The invention maximizes the time and hence the power transferred from a power management unit to the system (including the battery, in case of battery operated systems). The input current is reduced, thus increasing the input voltage in case of a high voltage drop across the internal resistance including interconnections between power source and power management unit. |
