Power Integrations RDK-710 Reference Design Kit

Power Integrations RDK-710 Reference Design Kit is a 1.4A at 5V and 0.42A at 12V dual output power supply using the InnoSwitch™ 3-TN INN3074M ICs. The INN3074M is a high-efficiency offline IC with a 725V primary MOSFET, synchronous rectification, and integrated secondary-side control. This Power Integrations RDK-710 Reference Design uses a flyback topology and provides 12W output from 85V_AC to 265V_AC with an 85% efficiency.

Features

12W output from 85V_AC to 265V_AC
Built-in synchronous rectification for > 85% efficiency at nominal AC input
All the benefits of secondary-side control with the simplicity of primary-side regulation
- Insensitive to transformer variation
- Extremely fast transient response independent of load timing

< 10mW no-load input power typically
< 260mW standby input power at 5V / 30mA load
Primary sensed output overvoltage protection (OVP) eliminates optocoupler for fault protection
Accurate thermal protection with hysteretic shutdown
