LTC3808EDE Description

Short technical summary and product information.

The LTC3808EDE from LT is a synchronous DC/DC switching controller designed for efficient power management. It features a constant frequency current mode operation for excellent transient response and supports external MOSFETs. The controller includes programmable output voltage tracking and a sense resistor optional design, allowing for flexibility in implementation.

 

Key electrical specifications include a wide input voltage range from 2.75V to 9.8V and an output voltage range from 0.6V up to the input voltage. It incorporates a precise 0.6V ±1.5% reference voltage. The device supports low dropout operation with 100% duty cycle and offers selectable Burst Mode, Pulse Skipping, or Forced Continuous operation.

 

The switching frequency can be programmed between 250kHz and 750kHz, or externally synchronized within this range for noise-sensitive applications. Spread spectrum modulation is integrated to reduce EMI. The LTC3808EDE is available in a tiny, thermally enhanced DFN package (4mm x 3mm) or a 16-lead SSOP package, suitable for surface mounting.

 

This controller is well-suited for battery-powered devices, notebook computers, portable instruments, and distributed DC power systems requiring high efficiency and stable voltage regulation.
