A power stage output node stabilizer may be used to reduce ringing of a power stage output node of a switching DC-DC power converter. The power stage output node stabilizer may be a network of resistors and switches coupling the power stage output node to a higher voltage level and a lower voltage level.

Switching regulator stability control circuit and methodology

Present invention is an apparatus and method for power conversion charge pumps that uses cross-coupling capacitors. High efficiency power converter charge pump for both divide by 3 (&#x2153;), divide by 3/2 (&#x2154;) are explicitly discussed. The power conversion charge pumps utilizing cross coupled capacitors may provide up to 40% reduction in a number of switches required for a charge pump implementation, thus reducing design area cost while also resulting in high-efficiency performance.

Apparatus and method for charge pump power conversion

A voltage regulator utilizes a non-invasive sensing capacitor in differentially sensing a current indicative of current of an output capacitor of the voltage regulator. Some embodiments utilize current mirrors and an inverter for determining if the current indicative of current of the output capacitor is above or below a particular magnitude. Some embodiments utilize information indicative of output capacitor current in determining duty cycle for a switching voltage regulator, and some embodiments utilize the information in activating transient control circuitry.
