Descriptions:

The STR-Z1504 is designed for high-efficiency power supply applications, particularly in AC-DC converters and resonant power supplies. It integrates control logic, gate drivers, and protection circuits for half-bridge topologies, making it suitable for TV power supplies, LED drivers, and industrial power systems.

Features:

1. Half-Bridge Resonant Control: Optimized for LLC or ZVS (Zero Voltage Switching) topologies.

2. Built-in Protections: Includes OCP, OVP, TSD, and UVLO for safe operation.

3. Low Standby Power: Enhances energy efficiency in standby mode.

4. Soft-Start Function: Reduces inrush current during startup.

5. Frequency Modulation: Adjusts switching frequency for optimal performance under varying loads.

6. High Integration: Reduces external component count for compact designs.
