STRX6769 - Brand New SK AC DC Converters, Offline Switchers
-
Description
The STRX6769 is an electronic component model in the AC DC Converters and Offline Switchers product category. It is a power IC designed for quasi-resonant type switching power supplies. The STRX6769 incorporates a power MOSFET and a controller IC, providing high efficiency and low noise power supply systems through its quasi-resonant operation and bottom-skip quasi-resonant operation. The STRX6769 is part of the STR-X6700 series, with the TO-220F package version available as the STR-W6700 series.
Specifications and Features
- Multi-Mode Control: The STRX6769 offers operation mode switching with three steps based on load conditions to achieve optimal high efficiency and low noise power supply systems across the full load range. Different functions may vary depending on the specific product within the series.
- Standby Mode: Under standby load conditions, the STRX6769 can be switched to UVLO intermittent oscillation by low output voltage through a standby signal or switched automatically via auto burst-oscillation.
- Bottom-Skip Quasi-Resonant Operation (Bottom-Skip QR): Under low to middle load conditions, the STRX6769 utilizes this operation mode.
- Quasi-Resonant Operation (QR): Under middle to rating (or heavy) load conditions, the STRX6769 performs quasi-resonant operation.
- Current-Mode Control
- Built-in PWM Oscillator: The PWM operates with a minimum frequency of around 22 kHz until the quasi-resonant signal becomes valid. This helps reduce stress on components during startup and load-shorted situations.
- Soft-Start Function
- Step-Drive Function: This function aims to reduce switching noise.
- Built-in Maximum ON Time Limitation Circuit: The function limits the maximum ON time of the power MOSFET during transitions at low input voltage and power ON/OFF.
- Input Compensation at Overcurrent: The function reduces the distortion of the overcurrent operation point to AC input voltage changes by adding three components.
- Built-in Avalanche Energy Guaranteed High-Voltage Power MOSFET
- Various Protections: The STRX6769 provides overcurrent protection (Pulse-by-Pulse), overload protection (Latch Shutdown), and overvoltage protection (Latch Shutdown).
Application Scenarios
The STRX6769 is commonly used in switching power supplies for various digital consumer equipment including LCD-TVs, PDP-TVs, CRT-TVs, home appliances, OA equipment, industry machines, communication devices, and others.
