PRODUCT DESCRIPTION
Series STR-W6750 Off-Line Quasi-Resonant Switching
Regulators
INTRODUCTION The Series STR-W6750 devices are hybrid integrated circuits (HICs) with a built-in power MOSFET and a control IC designed for quasi-resonant type switch-mode power supplies (SMPS).
In normal operation, the HIC provides high efficiency and low EMI noise with bottom-skip quasi-resonant operation during light output loads.
Low power consumption is also achieved by blocking (intermittent) oscillation during an auto-burst mode and reduced even further in a manually triggered (clamping an output voltage) standby mode.
The HIC is supplied in a seven-pin ful...
