Abstract

A conventional boost converter has a high power efficient CMOS adaptive controlled boost step-up LED drive implemented in BCD technology [1]. A novel adaptive minimum frequency control provides up to 52v from a single battery 4.5v input supply to ten series connected LEDs at the output. The proposed control scheme provides an accurate load current while achieving high power efficiency than conventional fixed on time schemes. TPS40211 and TPS40210are able to switch between PWM (pulse width modulation) automatically by calculating the feed backs from the inductor and LEDs current. This controller is functional from light to heavy loading situations which critical in improvement of power efficiency and battery life-time for high boost ratio applications in order as provide accurate LED current [10].
