摘要： Circuits and related methods for energy efficient battery supplied switching DC-to-DC regulators are disclosed. When entering a power-down state the energy in an output capacitor is harvested and charged back to the battery. This is achieved by ramping-down a reference voltage after a power-down sequence is initiated. The output voltage of the regulator is ramped-down accordingly. At the end of the power down sequence the output voltage of the regulator is down to 0V. The disclosure is especially important for regulators, which frequently are started up and switched down.

摘要： An apparatus and method for a bandgap voltage reference circuit with improved operation for a low voltage power supply. A bandgap voltage reference circuit which is operable at low power supply voltage for power supplies of 1.3V comprising of a first npn bipolar transistor, a second npn bipolar transistor, a third npn bipolar transistor, a first resistor, a second resistor, a third resistor, a fourth resistor, and a first, second and third p-channel MOSFET.

摘要： A switching regulator with an output high threshold voltage setting and an output low threshold voltage setting that permits a plurality of different operating modes to be established. Combined with these two threshold voltages is the ability to adjust both threshold voltages over the full range of the regulator output voltage, which yields switching regulator modes of forced normal operation, automatic where the operating mode is dependent upon output current and forced sleep mode.
