DESCRIPTION
FEATURES
Burst mode operation and● PWM operation with adjustable limiting current very low device consumption help to meet the
● 30 mW standby power at 265 Vac
● Operating frequency: standby energy saving regulations. Advance frequency jittering reduces EMI filter costs. Brownout function protects the switch mode – 60 kHz (L type), 115 kHz (H type) power supply when the rectified input voltage
● Frequency jittering for low EMC
● Output overvoltage protection level is below the normal minimum level specified for the system. Table 1.
