The LP62702 is designed to supply positive/negative driven applications. The device uses a single inductor scheme to provide up to 200mA currents for both positive and negative output. 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 OUTP and the charge pump provides a regulated and programmable negative bias OUTN. The device offers low noise, small solution size, high efficiency and robust protections. The other features include under-voltage lockout (UVLO), internal soft-start, boost cycle-by-cycle current limit, output over current and short circuit protection as well as thermal shutdown. The LP62702 is available in a space saving DFN3x3 package.
