Analog Devices LTC3307

5V, 3A Synchronous Step-Down Silent Switcher in 2mm x 2mm LQFN

Overview

TopologyBuck Converter
Input voltage2.25-5.5 V
Switching frequency3000 kHz
Output 11.2 V / 3 A

Description

The LTC®3307A is a very small, high efficiency, low noise, monolithic synchronous 3A step-down DC/DC converter operating from a 2.25V to 5.5V input supply. Using constant frequency, peak current mode control at switching frequencies up to 3MHz and minimum on-time as low as 22ns, this regulator achieves fast transient response with small external components. Silent Switcher architecture minimizes EMI emissions.

Features

  • High Efficiency: 8mΩ NMOS, 31mΩ PMOS
  • Programmable Frequency to 3MHz
  • Tiny Inductor and Capacitors
  • Peak Current Mode Control
  • 22ns Minimum On-Time
  • Wide Bandwidth, Fast Transient Response
  • Silent Switcher™ Architecture
  • Ultralow EMI Emissions
  • Low Ripple Burst Mode® Operation with IQ of 40μA

Typical applications

  • Optical Networking, Servers, Telecom, Communications
  • Industrial
  • Automotive
  • Distributed DC Power Systems (POL), FPGA, ASIC, μP Core Supplies
