STR-W6765 Descrição geral
A powerhouse within the realm of power ICs, the STR-W6765 offers an unmatched combination of performance and reliability. Boasting an integrated power MOSFET and PWM controller, this device simplifies power supply design while keeping costs in check. Its high switching frequency of up to 100 kHz facilitates efficient power conversion, contributing to overall energy savings. For added peace of mind, the STR-W6765 comes equipped with essential protection features including overvoltage protection, overcurrent protection, and thermal shutdown. The built-in soft-start function further enhances its usability by preventing excessive inrush current during startup
Características
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 lowering 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
Aplicativo
Switching Power Supplies for Digital Consumer Equipment;
LCD-TVs, PDP-TVs, CRT-TVs, etc., Home Appliances, OA Equipments,
