STRW6000S datasheet, circuit
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

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 performance-
to-cost power supply.
Applications:
Switching power supplies for electronic devices such as:
• Home appliances
• Digital appliances
• Office automation (OA) equipment
• Industrial apparatus
• Communication facilities
