linear DESIGN FEATURES LTMag-V18N01-05-LTM4605_07-MXie service manual
The LTM4605 and LTM4607 are surface-mount uModule regulators that simplify high power density supply design by integrating the switching controller, power FETs, and support components. These devices handle inputs up to 36V with efficiencies reaching 92% in boost mode and 97.7% in buck mode.
The document details the internal synchronous 4-switch architecture, operation modes (buck, boost, transition), and efficiency characteristics. It also covers PolyPhase paralleling techniques for higher current applications and provides critical PCB layout guidelines to minimize EMI and thermal stress.
