LTC3416
4A, 4MHz, Monolithic
Synchronous Step-Down
Regulator with Tracking U FEATURES DESCRIPTIO ■ The LTC®3416 is a high efficiency monolithic synchronous, 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 67mΩ of on-resistance increases efficiency and eliminates the need for an external Schottky
diode. Switching frequency is set by an external resistor.
100% duty cycle provides low dropout operation extending battery life in portable systems. OPTI-LOOP® compensation allows the transient response to be optimized over
a wide range of loads and output capacitors. ■
