PWM Off-Line Switching Regulator ICs
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

Description
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.
Applications:
Switching power supplies for electronic devices such as:
• White goods
• Consumer electronics
• Office automation
• Industrial equipment
• Communication equipment
