Abstract

A method and system are disclosed for improving the efficiency of a battery supplied power supply system. More particularly, a method and system is provided for improving the voltage regulation efficiency for a system in which the input voltage that is to be regulated may vary widely. In the techniques disclosed, the voltage supply that is utilized for the drive control circuitry of the voltage regulators is varied in relation to variations in the input voltage. Thus in one embodiment, the voltage supply that is utilized for the circuitry that drives a control terminal of the output transistor of the regulation circuitry may be varied in relation to variations in the input voltage. For example, an inverse relationship may be established between the input voltage level and the voltage level that is used for the gate drive circuitry that controls the gates of regulator output transistors.

Description

technical field [0001] The present invention relates to techniques for controlling voltage regulators, and more particularly to techniques for controlling voltage calibrators to extend battery life. Background technique [0002] Battery-backed power supplies are used in a variety of applications. Often battery power must be conditioned before it can be used in a system. For example, an exemplary system using a voltage regulator in a battery backed power system 100 is shown in FIG. 1 . As shown in Figure 1, for example, AC power is available through an AC adapter 110 connected to a public AC grid, as is a battery 120 provided to provide battery power. Switches 112 , 114 , and 116 and charger regulator 130 may be provided to select AC power from AC adapter 110 or battery power from battery 120 to power supply rail Vin 125 as is known in the art. It is also known to control the switch to provide battery charging. For example, co-pending application number 11 / 058,781 filed F...
