- Primary-Side Regulation (PSR) Eliminates Opto-
Coupler.
- ±5% Voltage and Current Regulation.
- 130-kHz Maximum Switching Frequency Enables
High-Power Density Charger Designs.
- Quasi-Resonant Valley-Switching Operation for
Highest Overall Efficiency.
- Patent-Pending Frequency-Jitter Scheme to Ease
EMI Compliance.
- Wide VDD Range Allows Small Bias Capacitor.
- Clamped Gate-Drive Output for MO.
