Details
Featuring an outstanding hybrid design, the STR-X6759N is a versatile IC that excels in high-voltage, high-speed switching applications within power supplies and electronic systems. Tailored for TV and monitor power supply circuits, it integrates a MOSFET and control circuitry to enhance performance and efficiency. Boasting a wide input voltage range and the ability to handle up to 650V, it is a well-suited solution for a myriad of power supply applications. With built-in protection features such as overcurrent, overvoltage, and thermal shutdown protection, safety is a top priority for the STR-X6759N. Operating at a maximum switching frequency of 65 kHz and a maximum output current of 8A, this IC delivers reliable performance. Furthermore, its integrated functions like soft-start, auto-restart, and frequency jittering contribute to improved operational reliability and efficiency
Key Features
- Multi-Mode Control
- The operation mode switching with three steps according to load conditions achieves the optimal high efficiency and low noise power supply systems across the full load range. (The confirmation of product number is necessary because some functions are different in each product.)
- In Standby (Under Standby Load Conditions):
- －UVLO Intermittent Oscillation by low output voltage --- Switched by Standby Signal, or
- －Auto Burst-Oscillation --- Switched Automatically
- Under Low to Middle Load Conditions: Bottom-Skip Quasi-Resonant Operation (Bottom-Skip QR)
- Under Middle to Rating (or Heavy) Load Conditions: Quasi-Resonant Operation (QR)
- Current-Mode Control
- Built-in PWM Oscillator
- The PWM operates with the minimum frequency of around 22 kHz, until the quasi-resonant signal becomes valid, reduces the stress on components at startup and load-shorted.
- Soft-Start Function
- Step-Drive Function, reducing switching noise
- Built-in Maximum ON Time Limitation Circuit
- The function limits the maximum ON time of power MOSFET, during the transitions at low input voltage, power ON/OFF.
- Input Compensation at Overcurrent
- The function reduces the distortion of overcurrent operation point to AC input voltage change by adding three components.
- Built-in Avalanche Energy Guaranteed High-Voltage Power MOSFET
- Various Protections
- Overcurrent Protection (OCP) -------------------------------Pulse-by-Pulse
- Overload Protection (OLP)-----------------------------------Latch Shutdown
- Overvoltage Protection (OVP)-------------------------------Latch Shutdown
