STRA6069H Overview
The STR-A6059H, STR-A6061H, STR-A6062H, and STR-A6069H 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:.
STRA6069H Key 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 ▫ Lig
- No load power consumption < 25 mW
- Operating frequency, fOSC(AVG)(typ) = 100 kHz
- Random Switching function: reduces EMI noise, and simplifies EMI filters
- Slope pensation function: avoids subharmonic oscillation
- Leading Edge Blanking function
