1 / 26 page Off-Line PWM Controllers with Integrated Power MOSFET STR3A400 Series Data Sheet STR3A400-DSE Rev.2.1 SANKEN ELECTRIC CO.,LTD. 1 Sept. 18, 2015 http://www.sanken-ele.co.jp/en/ © SANKEN ELECTRIC CO.,LTD. 2014 Description The STR3A400 series are power ICs for switching power supplies, incorporating a MOSFET and a current mode PWM controller IC. The low standby power is accomplished by the automatic switching between the PWM operation in normal operation and the burst-oscillation under light load conditions. The product achieves high cost-performance power supply systems with few external components. Features ● Low Thermal Resistance Package ● Improving circuit efficiency (Since the step drive control can keep VRM of secondary rectification diodes low, the circuit efficiency can be improved by low VF) ● Current Mode Type PWM Control ● Soft Start Function ● Automatic Standby Function No Load Power Consumption < 15mW ● Operation Mode Normal Operation -----------------------------PWM Mode Light Load Operation ------------------------ Green-Mode Standby ---------------------------- Burst Oscillation Mode ● Random Switching Function ● Slope Compensation Function ● Leading Edge Blanking Function ● Bias Assist Function ● Protections Two Types of Overcurrent Protection (OCP): Pulse-by-Pulse, built-in compensation circuit to minimize OCP point variation on AC input voltage Overload Protection (OLP): Auto-restart Overvoltage Protection (OVP): Latched shutdown or auto-restart Thermal Shutdown (TSD): Latched shutdown or auto-restart with hysteresis Typical Application VAC C1 C5 R1 D1 D2 R2 C2 T1 D51 C51 R51 R52 U51 R54 R56 C52 D P S PC1 PC1 C3 ROCP BR1 R53 R55 L51 C53 C4 VOUT GND 1 2 3 4 D/ST D/ST VCC NC S/OCP FB/OLP GND D/ST D/ST 8 7 6 5 STR3A400 U1 CY TC_STR3A400_1_R2 Package DIP8 Not to Scale Lineup ● Electrical Characteristics fOSC(AVG)(typ.) = 65 kHz VDSS(min.) = 650 V Products OVP, TSD Operation STR3A45× Latched shutdown STR3A45×D Auto-restart ● MOSFET ON Resistance and Output Power, P OUT* Products RDS(ON) (max.)
