STR-X6756 Descrizione generale

The STR-X6756 stands out as a universal-input, 17-pin monolithic flyback switch-mode regulator IC, delivering exceptional performance and protection features for LED lighting power supplies. Its wide input voltage range, advanced power MOSFET, and soft-start function make it a reliable and efficient choice for demanding LED lighting applications. With its pulse-by-pulse current limit and comprehensive protection mechanisms, it ensures safe and stable operation, even under challenging load conditions

Caratteristiche principali

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
