Overview

The UCC12041-Q1 device integrates a high-efficiency, low-emissions isolated DC/DC converter. This approach provides typically 500 mW of clean, steady power across a 3000-VRMSbasic isolation barrier.

The integrated DC/DC converter uses switched mode operation and proprietary circuit techniques to reduce power losses and boost efficiency. Specialized control mechanisms, clocking schemes, and the use of an on-chip transformer provide high efficiency and low radiated emissions.

The VINP supply is provided to the primary power controller that switches the power stage connected to the integrated transformer. Power is transferred to the secondary side, rectified, and regulated to a level set by the SEL pin condition.

A fast feedback control loop monitors VISO and the output load, and ensures low overshoots and undershoots during load transients. Undervoltage lockout (UVLO) with hysteresis is integrated on the VINP supply, which ensures robust system performance under noisy conditions.

UCC12041-Q1 is suitable for applications that have limited board space and require more integration. These devices are also suitable for very-high voltage applications, where power transformers meeting the required isolation specifications are bulky and expensive.
