Linear Technology LTC3838 Dual DC/DC Controller Datasheet
The LTC3838 is a dual-channel DC/DC controller designed for demanding low output voltage and high load current applications. It utilizes a controlled on-time architecture that supports switching frequencies from 200kHz to 2MHz, enabling the use of smaller components while maintaining efficiency at heavy loads.
A key feature of this device is its proprietary Detect Transient Release (DTR) capability, which improves transient performance in low output voltage applications by detecting load releases and reducing overshoot. The controller supports differential regulation accuracy of +0.67% and can be configured for dual or single-output applications with per-channel currents up to 25A.
