45nm direct battery DC-DC converter for mobile applications
… efficiently interface the low voltage, low power digital baseband and DSP of the mobile phone with the battery which maybe at voltages as high as 4.2V. This is efficiently done by a DC-DC converter which is a separate IC designed on an older generation process capable of handling high voltages. …

Current-Mode Control: Modeling and its Digital Application
… current, one of state variables, is used in the modulator in current-mode control while an external ramp is used in voltage-mode control. The dynamic nonlinearity of current-mode control results in the difficulty of obtaining the small-signal model for current-mode control in the frequency …

Modeling and Design of Digitially Controlled Voltage Regulator Modules
It can be expected that digital controllers will be increasingly used in low voltage, high-current and high frequency voltage regulator modules (VRMs) where conventional analog controllers are currently preferred because of the cost and performace reasons. However, there are still remaining two …
