Overview
| Topology | Flyback Converter |
| Input voltage | 120-375 V |
| Switching frequency | 54-66 kHz |
| Output 1 | 12 V / 1 A |
| IC revision | 1 |
Description
The device is an off-line converter with an 800 Vavalanche ruggedness power section, a PWMcontroller, user defined overcurrent limit,protection against feedback networkdisconnection, hysteretic thermal protection, softstart up and safe auto restart after any faultcondition.Advance frequency jittering reduces EMI filtercost. Burst mode operation and the devices verylow consumption both help to meet the standardset by energy saving regulations
Features
800 V avalanche rugged power section
- PWM operation with frequency jittering for lowEMI
- Operating frequency:– 60 kHz for L type– 115 kHz for H type
- Standby power < 50 mW at 265 VAC
- Limiting current with adjustable set point
- On-board soft-start
- Safe auto-restart after a fault condition
- Hysteretic thermal shutdown
Typical applications
- LED drivers
- Auxiliary power supply for appliances
- Power metering
- SMPS for set-top boxes, DVD players and recorders
