FEATURES
Dual 5V, 2A Synchronous Step-Down
DC/DCs in Tiny LQFN and WLCSP
The LTC®3315A features dual 2A monolithic synchronous
step-down converters operating from a 2.25V to 5.5V
input supply in one package for space-constrained appli
cations with demanding performance requirements. Using
constant frequency, peak current mode control at switch
ing 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
skipping mode for low noise or in Burst Mode® opera
tion 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 and a
1.64mm × 1.64mm WLCSP package.
