W6750 - STRW6750

Datasheet Summary

Description

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).

Features

  • Blocking (or intermittent) oscillation operation by reducing output voltage in the standby mode. In addition to the standard quasi-resonant operation, a bottom-skip function is available for increased efficiency from light to medium load. Soft-start operation at start-up. Reduced switching noise (compared to conventional PWM hard-switching solution) with a step-drive function. Built-in avalanche-energy-guaranteed power MOSFET (to simplify surge-absorption circuit; no VDSS derating is required).

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.
