STRS5706

The STRS5706 is designed as one kind of off-line switching regulators - with bipolar switching transistor that incorporates the primary control and propor-tional drive circuit with a third-generation high-voltage bipolar switching transistor. And this device and its fixed-frequency counterparts represents a significant advance in off-line SMPS reliability growth and integration, has been provened.

Features of the STRS5706 are:(1)quasi-resonant operation for low EMI and high efficiency; (2)low-power output standby mode; (3)indirect feedback from auxiliary winding reduces external component count; (4)pulse-by-pulse over-current protection; (5)latched over-voltage and thermal protection; (6)third-generation switching transistor with proportional drive; (7)maximum on time and off time set during manufacture; (8)internal under-voltage lockout with hysteresis; (9)over-molded SIP with integral isolated heat spreader.

The absolute maximum ratings of the STRS5706 can be summarized as:(1)Supply Voltage: 15 V;(2)Output Voltage: 850 V;(3)Continuous Output Current: See Table;(4)Sink Current: 1.5 A;(5)Drive Current: -700 mA;(6)Inhibit Voltage:15 V;(7)Over-Current Protection Voltage Range: ±3.5 V;(8)Insulation Voltage: 2000 V;(9)Package Power Dissipation: See Graph;(10)Output Junction Temperature: +150°C.etc. If you want to know more information about the STRS5706, please download the datasheet in www.seekic.com or www.chinaicmart.com .
