ALT80802 Datasheet (Allegro) - Buck-Boost or Buck 2 Amp LED Driver

ALT80802, Buck-Boost or Buck 2 Amp LED Driver

The ALT80802 is a high-frequency switching regulator that provides constant output current to drive high-power LEDs.

It integrates a power MOSFET for step-down or inverting buckboost conversion.

With current-mode control and simple external compensation, theALT80802 can achieve fast transient respon
