STR-W6000S Series PWM Off-Line Switching Regulator ICs Features and Benefits ▪ Current mode PWM control ▪ Brown-In and Brown-Out function: auto-restart, prevents excess input current and heat rise at low input voltage ▪ Auto Standby function: improves efficiency by Burst mode operation in light load ▫ Normal load operation: PWM mode ▫ Light load operation: Burst mode ▪ No load power consumption < 30 mW ▪ Operating frequency, fOSC(AVG)(typ) = 67 kHz ▪ Random Switching function: reduces EMI noise, and simplifies EMI filters ▪ Slope Compensation function: avoids subharmonic oscillation ▪ Leading Edge Blanking function Continued on the next page… Package: TO-220F-6L Not to scale Description The STR-W6051S, STR-W6052S, and STR-W6053S are power ICs for switching power supplies, incorporating a power MOSFET and a current mode PWM controller IC in one package. To achieve low power consumption, these products include a startup circuit and a standby function in the controller. The switching modes are automatically changed according to load conditions: in normal operation, PWM mode, and in light load conditions, burst mode. The rich set of protection features helps to realize low component counts, and high performanceto-cost power supply. Applications: Switching power supplies for electronic devices such as: • Home appliances • Digital appliances • Office automation (OA) equipment • Industrial apparatus • Communication facilities Typical Application Circuit VAC BR1 C1 C(CR) damper snubber CRD clamp snubber T1 D51 L51 U1 STR-W6000S C5 R1 D1 P RA C51 S PC1 R52 R51 R55 C52 R54 R53 U51 R56 1 34567 RB D2 R2 VOUT C53 GND D/ST S/ OCP V CC GND FB / OLP BR C4 ROCP C10 C3 PC1 RC C2 D C9 STR-W6000S-DS SANKEN ELECTRIC CO., LTD. http://www.sanken-ele.co.jp/en/ February 27, 2013 STR-W6000S Series PWM Off-Line Switching Regulator ICs Features and Benefits (continued) ▪ Audible Noise Suppression function during Standby mode ▪ Protection features ▫ Overcurrent protection (OCP): pulse-by-pulse, with input compensation function ▫ Overvoltage protection (OVP): auto-restart ▫ Overload protection (OLP): auto-restart, with timer ▫ Thermal shutdown protection (TSD): auto-restart Selection Guide Part Number Power MOSFET VDSS(min) (V) RDS(ON)(max) (Ω) Output Power*, POUT (W) 230 VAC 85 to 265 VAC STR-W6051S 650 3.95 45 30 STR-W6052S 650 2.8 60 40 STR-W6053S 650 1.9 90 60 *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.
