ADI LTC3315BMPV#TRPBF

降压降压2.25V5.5V2A，2A

Overview

The LTC3315AEV#TRMPBF features dual 2A monolithic synchronous step-down converters operating from a 2.25V to 5.5V input supply in one package for space-constrained applications with demanding performance requirements. Using constant frequency, peak current mode control at switching frequencies up to 3MHz with a minimum on-time as low as 25ns, both bucks achieve high efficiency and fast transient response in a very small application footprint.

The LTC3315AEV#TRMPBF can regulate outputs as low as 500mV. Other features include precision enable thresholds, a PGOOD signal, output overvoltage protection, thermal shutdown, output short-circuit protection, and up to 100% duty cycle operation for low dropout. The LTC3315AEV#TRMPBF is available in a compact 2mm × 2mm LQFN package.
