Regulator design for inductive booster pump using pulse width modulation technique

摘要: A DC voltage boost circuit including a regulation that produces pulse width modulated control signal for regulating the output of circuit. Various embodiments circuits are disclosed. In one embodiment, includes waveform generator generating triangular and comparator producing by comparing with varies proportional to booster voltage. another sawtooth whose rise time inversely substantially constant Yet, in counter count sequentially cycles response clock signal, wherein is reset change voltage, logic from count.
