2 / 14 page 2 SANKEN ELECTRIC CO., LTD. STR3A150-DS July 20, 2012 PWM Off-Line Switching Regulator ICs STR3A151, STR3A152, STR3A153, STR3A154, STR3A155 Features and Benefits (continued) • Soft Start function: reduces stress on internal power MOSFET and secondary output rectifier diode at startup • Protection Functions: ▫ Overcurrent Protection function (OCP); pulse-by-pulse, built-in compensation circuit to minimize OCP point variation on AC input voltage ▫ Overload Protection function (OLP); auto restart, built-in timer, reduces heat during overload condition, and no external components required ▫ Overvoltage Protection function (OVP); latched shutdown ▫ Thermal Shutdown function (TSD); latched shutdown Selection Guide Part Number fOSC (kHz) MOSFET POUT* (W) OVP/TSD VDSS(min) (V) RDS(on)(max) (Ω) 230 VAC 85 to 265 VAC STR3A151 67 650 4.0 24 16 Latched STR3A152 3.0 30 23 STR3A153 1.9 36 30 STR3A154 1.4 40 32 STR3A155 1.1 43 35 *The listed output power is based on the thermal ratings, and the peak output power can be 120% to 140% of the value stated here. At low output voltage and short duty cycle, the output power may be less than the value stated here. |
