Datasheet
2.1V(or 2.5V) to 5.5V, 1.5A 1ch
Boost Converter with Integrated FET
BD8152FVM BD8158FVM
General Description
BD8152FVM and BD8158FVM are 1-Channel boost
converter which uses low voltage FET. The input
voltage is 2.5V to 5.5V for BD8152FVM and 2.1V to
5.5V for BD8158FVM achieving a low power
consumption. The high accuracy feedback voltage
(±1%) is established and the brightness dispersion of
TFT-LCD panel is suppressed.
