SNVSBJ0B December 2019 – August 2021 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.
