DC397 Demonstration Circuit Quick Start Guide for LT1930A and LT1931A DC/DC Converters
Quick start guide for the DC397 demonstration circuit featuring LT1930A and LT1931A regulators for boost, SEPIC, and inverting DC/DC converter applications.
Overview
The DC397 demonstration circuit showcases the LT1930A and LT1931A high-power switching regulators in SOT-23 packages. This multipurpose board includes three separate converter topologies: a boost circuit (5V to 12V/250mA), a SEPIC circuit (10V-16V input to 12V/250mA), and an inverter circuit (+12V to -12V/250mA). These designs demonstrate the 2.2MHz high-speed switching frequency, internal 36V/1A integrated switches, and compact component footprints required for space-constrained electronics.
