The LTC3411EMS#PBF is a constant frequency, synchronous, step-down DC/DC converter from Linear Technology Corporation, suitable for medium power applications. It operates from a 2.63V to 5.5V input voltage range and features a user-configurable operating frequency up to 4MHz. This allows for the use of small, low-cost capacitors and inductors, with heights of 2mm or less.
Key electrical specifications include internal synchronous power switches with a 1.6A peak current rating and low RDS(ON) of 0.11Ω, contributing to high efficiency up to 95%. The output voltage is adjustable from 0.8V to 5V. The device supports low dropout operation with a 100% duty cycle and maintains low quiescent current of 60μA, reducing battery consumption. In shutdown mode, current draw is less than 1μA.
The converter utilizes current mode architecture for excellent line and load transient response, and can be configured for automatic power-saving Burst Mode operation. For reduced noise, the SYNC/MODE pin can be set to skip pulses or provide forced continuous operation. The LTC3411EMS#PBF is available in small 10-lead MSOP or DFN packages, suitable for space-constrained designs.
Applications for this converter include notebook computers, digital cameras, cellular phones, handheld instruments, and board-mounted power supplies.
