Description

  • Typical Application for LTC3564 - 2.25MHz, 1.25A Synchronous Step-Down Regulator. The LTC3564 is a high efficiency monolithic synchronous buck regulator using a constant frequency, current mode architecture. Supply current during operation is only 20uA, dropping to =1uA 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

Key Features

  • Conversion Type
    DC to DC
  • Output Current
    1.25 A
  • Topology
    Buck- Synchronous
