Linear Tech has announced a synchronous step-down DC/DC controller that operates at up to 2.25MHz for reduced circuit size and increased power density. Its 45ns minimum on-time enables 24VIN to 3.3VOUT conversions while switching at a fixed 2MHz, avoiding critical noise-sensitive frequency bands including AM radio. Synchronous rectification delivers up to 95% efficiency while Burst …
