20090153108 | Power management efficiency using DC-DC and linear regulators in conjunction - A power management unit for improving power efficiency of an electronic device. The power management unit includes a first and a second stage power regulator and a control circuitry. The first stage power regulator includes a switching regulator to efficiently adjust an input voltage based on a feedback signal. The adjusted input voltage provides the second stage power regulator that includes low dropout voltage regulators with an input voltage close to its output. Thus, power dissipation in the second stage is reduced by reducing the voltage differential between the input and desired output voltages. The second stage turns on/off power to units of the electronic device. The control circuitry generates the feedback signal based on dropout voltages of the low dropout voltages, the desired output voltage and the adjusted input voltage. The largest dropout voltage is selected and adds it to the desired output voltage to generate the feedback signal. | 06-18-2009 |
20090153211 | Integrated circuit device core power down independent of peripheral device operation - In an integrated circuit device, a circuit for maintaining asserted values on an input output pin of the device when a functional block of the device is placed in a sleep mode. The circuit includes an interface for coupling a functional block of a processor to an input and output pin and an output storage element coupled to the interface for storing a current value of the input output pin. The circuit further includes a sleep mode enable for controlling the output storage element to store the current value of the input output pin prior to the functional block being entering a sleep mode and cause the current value of the input output pin to remain asserted after the functional block is in sleep mode. The sleep mode enable is also to deactivate the storage element when the sleep mode is exited. | 06-18-2009 |
