LTC3315A & LTC3315B Step-Down Converters

Analog Devices LTC3315A and LTC3315B Synchronous Step-Down Converters feature dual 2A monolithic synchronous step-down converters operating from a 2.25V to 5.5V input supply in one package. This makes the converters ideal 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. This allows both bucks to achieve high efficiency and fast transient response in a very small application footprint.
