The LP6280A is designed positive/negative driven applications. The device uses a single inductor scheme to provide output currents. The integrated synchronous Boost converter provides a regulated voltage for a LDO and a charge pump. The LDO provides a regulated and programmable positive bias charge pump provides a regulated and programmable negative bias VON. offers low noise, small solution size and high efficiency. The other feature includes under lockout (UVLO), internal soft cycle-by-cycle current limit and output over load and short circuit protection shutdown. The LP6280A is available in a space and programmable positive bias charge pump provides a regulated and programmable negative bias VON. offers low noise, small solution size and high efficiency. The other feature includes under lockout (UVLO), internal soft cycle-by-cycle current limit and output over load and short circuit protection shutdown. The LP6280A is available in a space
