摘要: This document discusses, among other things, apparatus and methods for a boost converter start-up circuit. In an example, a start-up circuit can include a linear current generator configured to couple a supply terminal of the voltage converter to an output terminal of the voltage converter. The linear current generator can include a modified current mirror and a feedback circuit configured to provide a first representative of an output voltage of the output terminal to an input of each of a first and a second adjustable current source of the modified current mirror.

摘要: This document discusses apparatus and methods associated with an early warning strobe input of a boost converter. In an example, a method of increasing a set point of a boost converter configured to provide power to a mobile device can include receiving an indication that the mobile device will transition from the first low-power mode to a second higher-power mode; and increasing the set point of the boost converter in response to the indication.

摘要: Apparatus and methods of implementing a voltage converter bypass switch, among other things, are discussed herein. In certain examples, a boost converter can include a bypass switch configured to bypass an inductor and a transistor of the boost converter to more directly couple a supply voltage to an output of the boost converter during a bypass mode, and to isolate a supply voltage input from the output during a boost mode of the boost converter.
