Datasheet Summary
Low-Power Off-line Digital Green-Mode PWM Controller
1.0 Features
2.0 Description
- - Primary-side feedback eliminates opto-isolators and simplifies design
- - 64-kHz PWM switching frequency
- - No-load power consumption < 100 mW at 230 Vac with tight dynamic load transient response
- - Able to meet < 30 mW no-load power consumption with large value pre-load resistor
- - Adaptive multi-mode PWM/PFM control improves efficiency
- - Quasi-resonant operation for highest overall efficiency
- - EZ-EMI ® design to easily meet global EMI standards
- - Direct drive of low-cost BJT switch
- - Dynamic base current control
- - Very tight constant voltage and constant current regulation with...
