Resonant Flyback Switching Regulator. Drain Switching Current, I D. Peak Drain Switching Current,. Single-Pulse Avalanche Energy,. V OCP. Package Power Dissipation, P D. See Graph. Internal Frame Temp. Operating Temperature Range,. Storage Temperature Range,. The STR-W is a quasi-resonant regulator specifically designed. It incorporates a primary control and drive. The regulator exhibits.
A bottom-skip function. Covering the power range from below watts for a VAC. An auto-standby. An externally triggered standby mode. Multiple protections, including the. Cycle-by-cycle current limiting, undervoltage lockout with hyster-. Overvoltage protection is latched. The latch may be reset by cycling the input supply.
Low start-up current and a low-power standby mode selected from the. Simplified Surge Absorption. Quasi-Resonant Mode for Normal Operation. Always order by complete part number, e. Sanken Power Devices. Pulse-by-Pulse Overcurrent Protection. Overload Protection with Auto Recovery.
Latching Overvoltage Protection. Undervoltage Lockout with Hysteresis. The STR-W is a quasi-resonant regulator specifically designed to satisfy the requirements for increased integration and reliability in switch-mode power supplies.
A bottom-skip function minimizes an increase of operational frequency during light loads to improve system efficiency over the entire load range.
Covering the power range from below watts for a VAC input, or watts for a universal input 85 to VAC , this device can be used in a range of applications, from DVD and VCR players to ac adapters for cellular phones and digital cameras. An auto-standby function, which is internally triggered by sensing on time, reduces power consumption at light load. An externally triggered standby mode reduces the input power further.
Cycle-by-cycle current limiting, undervoltage lockout with hyster- esis, and overvoltage protection protect the power supply during the normal overload and fault conditions. Overvoltage protection is latched after a short delay.
Low start-up current and a low-power standby mode selected from the secondary circuit completes a comprehensive suite of features.
