STR-W6700 - (STR-W6700 Series) Quasi-Resonant Switching Regulators

General Description

28103.30 Figure 1.

STR-W6700 series packages are fully molded TO-220 package types.

Pin 2 is deleted for greater isolation.

Key Features

  • include the following:.
  • 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 surg.

Product Information STR-W6700 Series 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 quasiresonant 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.
