STR-W6200D Datasheet | Sanken

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 ponents. 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 pensation circuit: avoids subharmonic oscillation - Automatic Standby Mode function (Input Power < 40 m W 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 ponents - 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 pensation 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 ponents 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 - munications...
