Clocked ramp apparatus for voltage regulator softstart and method for softstarting voltage regulators

摘要

Methods and apparatus for softstarting a voltage regulation circuit. A circuit for generating an output voltage at an output thereof includes a capacitor having a first terminal configured to be coupled to a reference potential and having a second terminal coupled to the output, and a switchable current source coupled to the capacitor for intermittently charging the capacitor until the output voltage is reached.
