Description

BD8152FVM,BD8158FVM are the 1-channel step-up switching regulator which builds in the low voltage FET. Input voltage is 2.5 V to 5.5 V (BD8152FVM), 2.1V to 5.5V(BD8158FVM) realizing the low consumption power. High accuracy feedback voltage r1 is established and the brightness dispersion of TFT-LCD panel is suppressed.
