9 Performance Data
The ON/OFF control scheme employed by TinySwitch-III yields virtually constant
efficiency across the 25% to 100% load range required for compliance with EPA, CEC,
CECP and AGO energy efficiency standards for external power supplies (EPS). Even at
loads below 10% of the supply’s full rated output power, efficiency remains above 65%,
providing excellent standby performance for applications that require it. This performance
is automatic with ON/OFF control. There are no special burst modes that require the
designer to consider specific thresholds within the load range in order to achieve
compliance with global energy efficiency standards.
All measurements performed at room temperature, 60 Hz input frequency.
