MT3420SP Overview
The MT3420SP is a 1.5MHz constant frequency, current mode step-down converter. It is ideal for portable equipment requiring very high current up to 2A from single-cell Lithium-ion batteries while still achieving over 90% efficiency during peak load conditions. The MT3420SP also can run at 100% duty cycle for low dropout operation, extending battery life in portable systems while light load operation provides very...
