By co-packaging the high-side and low-side MOSFETs in a single SON-5 package, parasitic inductance between the two switches is minimized, reducing ringing and switching losses. The high-side MOSFET features 3.5 mOhm max RDS(on) and the low-side features 2.6 mOhm max RDS(on), enabling high efficiency at output currents up to 12 A. The integrated Schottky body diode in the low-side MOSFET reduces reverse recovery losses. The PowerPAD exposed pad provides excellent thermal performance for compact designs.","working_principle":"The CSD87351Q5D integrates two N-channel MOSFETs in a half-bridge configuration. The high-side MOSFET (control FET) connects the input voltage to the output inductor (SW node), and the low-side MOSFET (synchronous FET) connects the SW node to ground. During the on-time, the high-side MOSFET conducts, delivering energy to the inductor and load. During the off-time, the high-side turns off and the low-side MOSFET turns on, allowing the inductor current to freewheel through the low-side switch. The co-packaged design minimizes the parasitic loop inductance between the high-side drain, the SW node, and the low-side source, which reduces voltage overshoot and high-frequency ringing at the switch node. The integrated Schottky diode across the low-side MOSFET provides a low-forward-voltage path during the dead-time when both MOSFETs are off.","pin_description":"
