The LTC3408 1.5 MHz, synchronous buck regulator integrates a p-channel bypass MOSFET with an on-resistance of 0.08W into an eight-lead, 3 mm x 3 mm DFN package that can deliver up to 600 mA of ...
The on-chip bypass MOSFET has an RDS ON of only 0.08 Ω, minimizing power loss in the bypass mode. The LTC3408 uses a constant frequency, current mode architecture, which operates from an input voltage ...
