STR-W6753 STRW6753 STR W6753 STRW 6753 Switching Regulators IC

STR-W6753 STRW6753 STR W6753 STRW 6753 Switching Regulators IC

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)
