LX1742 Description
C OM The LX1742 is a pact high efficiency step-up boost controller. Featuring a pseudo-hysteretic pulse frequency modulation topology, the LX1742 was designed for maximum efficiency, reduced board size, and minimal cost. Utilizing an internal N-Channel MOSFET, the LX1742 offers designers maximum flexibility with respect to efficiency and cost.
