摘要： A boost power converter system according to one embodiment includes an input voltage high-side node; an inductor coupled to the input voltage high-side node at a first terminal of the inductor; a power switch coupled to the inductor at a second terminal of the inductor; a drive circuit configured to control the power switch such that the boost power converter system operates in a discontinuous conduction mode when a load current drops below a critical conduction threshold; and a damping switch configured to enable current flow from the power switch at the second terminal of the inductor to the input voltage high-side node, wherein the damping switch is closed when the power switch is open and the damping switch is opened when the power switch is closed.

摘要： A low battery detect circuit with digitally programmable detect levels. The programmable low battery detect circuit includes a comparator that compares a stable reference voltage against a battery-supplied voltage as divided down by a digitally programmable resistive divider chain. By programmably varying the resistance of the divider chain, the low battery detect threshold level can be varied depending on the requirements of the application.
