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.
Features
- 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.
