SNVSBJ0A December 2019 – June 2020 LM5170
PRODUCTION DATA.
An innovative average current mode control scheme maintains constant loop gain allowing a single R-C network to compensate both buck and boost conversion. The oscillator is adjustable up to 500 kHz and can synchronize to an external clock. Multiphase parallel operation is achieved by connecting two LM5170 controllers for 3- or 4-phase operation, or by synchronizing multiple controllers to phase-shifted clocks for a higher number of phases. A low state on the UVLO pin disables the LM5170 in a low current shutdown mode.
