The LTC
3416 is a high efficiency monolithic synchro-
nous, step-down DC/DC converter utilizing a constant
frequency, current mode architecture. It operates from an
input voltage range of 2.25V to 5.5V and provides a
regulated output voltage from 0.8V to 5V while delivering
up to 4A of output current. The internal synchronous
power switch with 67m
of on-resistance increases effi-
ciency and eliminates the need for an external Schottky
diode. Switching frequency is set by an external resistor.
100% duty cycle provides low dropout operation extend-
ing battery life in portable systems. OPTI-LOOP
compen-
sation allows the transient response to be optimized over
a wide range of loads and output capacitors.
The LTC3416 operates in forced continuous operation and
provides tracking of another power supply rail. Forced
continuous operation reduces noise and RF interference and
provides excellent transient response. Fault protection is
provided by an overcurrent comparator, and adjustable
compensation allows the transient response to be optimized
over a wide range of loads and output capacitors.
