STR-Z2500 Series
Power IC for Current Resonant Type Switching Power Supply
with Half-Bridge Resonance, High Efficiency and Low Noise
■ General Descriptions
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
Soft-Switched Multi-Resonant Zero Current Switch (SMZ)
SIP-24
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.
External Latch Protection (ELP)
The function enables the latch shutdown by external signal.
Built-in Avalanche Energy Guaranteed High-Voltage Power MOSFET
Various Protections
Overcurrent Protection (OCP)---------------------------------- Auto-Restart
Three-Step Protections Depending on Overcurrent Status
Overload Protection (OLP) ------------------------------------- Latch Shutdown
Overvoltage Protection (OVP) --------------------------------- Latch Shutdown
External Latch Protection (ELP) ------------------------------- Latch Shutdown
Thermal Shutdown Protection (TSD) ------------------------- Latch Shutdown
