Application Information STR-W6200D Series PWM Off-Line Switching Regulator ICs General Description The STR-W6200D series are power ICs for switching power supplies, incorporating a power MOSFET and a current mode PWM controller IC in one package. Including a startup circuit and a standby function in the controller, the product achieves low power consumption, low standby power, and high cost-effectiveness in power supply systems, while reducing external components. Features and Benefits ▪ TO-220 fully-molded package with 6 pins ▪ Current mode PWM control ▪ PWM and frequency modulation functions: reduces EMI noise, simplifies EMI filters, and cuts cost by external part reduction ▪ Built-in Slope Compensation circuit: avoids subharmonic oscillation ▪ Automatic Standby Mode function (Input Power < 40 mW at no load) ▫ Normal operation: PWM mode ▫ Light load operation: Standby mode (burst oscillation) ▪ Built-in Audible Noise Suppression function during Standby mode ▪ Built-in startup circuit: reduces power consumption in standby operation, and eliminates external components ▪ Bias-Assist function: improves startup operation, suppresses VCC pin voltage drop in operation, and allows use of smaller VCC capacitor ▪ Built-in Leading Edge Blanking function ▪ 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 few external components required ▫ External Latch Protection function (ELP): latched shutdown by external signal ▫ Overvoltage Protection function (OVP): latched shutdown ▫ Thermal Shutdown function (TSD); latched shutdown Figure 1. STR-W6200 series packages are fully molded TO-220 package types. Pin 2 is deleted for greater isolation. A flange is provided for heatsink mounting. Applications Switching power supplies for electronic devices such as: • White goods • Consumer electronics • Office automation • Industrial equipment • Communications equipment The product lineup for the STR-W6200D series provides the following options: Part Number STR-W6251D STR-W6252D STR-W6253D 67 650 fOSC (kHz) MOSFET VDSS(min) (V) RDS(on) (max) (Ω) 3.95 2.8 1.9 POUT- (W) 230 VAC 85 to 265 VAC 45 60 90 30 40 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. At low output voltage and short duty cycle, the output power may be less than the value stated here.
