NCV1397ADR2G

NCV1397ADR2G is a high performance resonant mode controller with integrated high-voltage driver. It is a high performance controller that can be utilized in half bridge resonant topologies such as series resonant, parallel resonant and LLC resonant converters. It integrates 600V gate drivers, simplifying layout and reducing external component count. With its unique architecture, including a 500KHz voltage controlled oscillator whose control mode permits flexibility when O-ring function is required, NCP1397 delivers everything needed to build a reliable and rugged resonant mode power supply. It provides suite of protection features with configurable settings to optimize any application. This includes auto recovery or fault latch off, brown out, open optocoupler, soft start and short circuit protection. Applications include flat panel display power converters, high power AC-DC adapters for notebooks, computing power supplies, industrial/medical power sources, offline battery chargers.

• Adjustable minimum switching frequency with ±3% accuracy
• Startup sequence via an externally adjustable soft start
• Brown out protection for a simpler PFC association
• Latched input for severe fault conditions, e.g. over temperature or OVP
• Timer based input with auto recovery operation for delayed event reaction
• Latched overcurrent protection
• Disable input for immediate event reaction or simple ON/OFF control
• Common collector optocoupler connection for easier O-ring
• Internal temperature shutdown
• 16 lead SOIC package, operating temperature range from -40°C to +125°C
