Product Overview

The LTC3564EDCB#TRMPBF is a high-efficiency monolithic synchronous Buck Regulator using a constant frequency and current-mode architecture. Supply current during operation is only 20µA, dropping to <=1µA in shutdown. The 2.5 to 5.5V input voltage range makes the LTC3564 ideally suited for single Li-ion battery-powered or 3.3 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. Switching frequency is internally set at 2.25MHz, allowing the use of small surface mount inductors and capacitors. The internal synchronous switch increases efficiency and eliminates the need for an external Schottky diode. Low output voltages are easily supported with the 0.6V feedback reference voltage.
  • No Schottky diode required
  • Current-mode operation for excellent line and load transient response
  • Over-temperature protection
  • Up to 96% high efficiency
