STR-W6753 STRW6753 STR W6753 STRW 6753 Switching Regulators IC BC89
Description: The STR-W6700 series products are power ICs for quasi-resonant type switching power supplies, incorporating a power MOSFET and a controller IC, The product achieves high efficiency and low noise power supply systems by the quasi-resonant operation and the bottom-skip quasi-resonant operation.
Feature: Multi-Mode Control -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 Soft-Start Function Step-Drive Function Built-in Maximum ON Time Limitation Circuit Input Compensation at Overcurrent Built-in Avalanche Energy Guaranteed High-Voltage Power MOSFET Protection functions: Overcurrent protection (OCP): pulse by pulse Overload protection (OLP): latch shutdown Overvoltage protection(OVP): latch
