Description
The iW1689 is a high performance AC/DC power supply controller which uses digital control technology to build sensorless peak current mode PWM flyback power supplies.
Features
- Primary-side feedback eliminates opto-isolators and simplifies design.
- Multi-mode operation for highest overall efficiency.
- Very tight output voltage regulation.
- No external compensation components required.
- Complies with CEC/EPA/IEC no load power consumption and average efficiency regulations.
- Built-in secondary constant-current control with primaryside feedback.
- Low start-up current (8 µA typical).
- Built-in soft s.
