Product Details

Demo circuit 1157 is a dual monolithic step-down DC/DC converter featuring the LT3510. The demo circuit is designed for 3.3V and 1.8V outputs from a 4.5V to 24V input. The current capability of each channel is up to 2A. Both regulators features independent input voltage, feedback, soft-start and power good pins and the outputs can be configured to track each other.
