The LTC3315A 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 LTC3315A operates in forced continuous or pulse skip mode for low noise or in Burst Mode® operation for high efficiency at light loads. The common buck switching frequency is 2MHz and can be synchronized to an external oscillator via the MODE/SYNC pin.
The LTC3315A 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 LTC3315A is available in a compact 2mm × 2mm LQFN package.
