■ The LTC ®3564 is a high efficiency monolithic synchronous buck regulator using a constant frequency, current
mode architecture. Supply current during operation is
only 20μA, dropping to ≤1μA in shutdown. The 2.5V to
5.5V input voltage range makes the LTC3564 ideally suited
for single Li-Ion battery-powered or 3.3V to 5V input
voltage applications. 100% duty cycle provides low dropout operation, extending battery life in portable systems.
Automatic Burst Mode® operation increases efficiency at
light loads, further extending battery runtime. High Efficiency: Up to 96% …
