STR-Z2586

STR-Z2500 ■ General Descriptions Series Power IC for Current Resonant Type Switching Power Supply with Half-Bridge Resonance, High Efficiency and Low Noise The STR-Z2500 series products are power ICs for current resonant type switching power supplies, incorporating a controller IC including high-side and low-side MOSFETs of half-bridge type resonance and a floating-drive circuit. The product achieves high efficiency and low noise power supply systems by the ZVS and ZCS. The product is recommended for high-efficiency small and standardized power supplies because of easy circuit designs with few external components. ■ Features SIP-24 Soft-Switched Multi-Resonant Zero Current Switch (SMZ) The zero-current switching (ZSC) and zero-voltage switching (ZVS) of half-bridge type resonance achieve the high efficiency and low noise systems. 24-pin SIP Package with Al-Fin (Sanken designation: SLA-24) The product incorporates two power MOSFETs and a controller IC, and achieves small and highly integrated systems by few external components and smaller area size. Built-in Startup Circuit Automatic Dead Time Adjustment Function for Wide Resonant Conditions Burst-Oscillation Function The function enables the stable output control at no load to light load conditions and improves the efficiency. Soft-Start Function Brown-In / Brown-Out Function The function enables the oscillation start/stop by externally rated input voltage and makes protections at low input voltage.
