NCP1398_13 Datasheet, PDF (1/24 Pages) ON Semiconductor – High Performance Resonant Mode Controller with Integrated High-Voltage Drivers

NCP1398B/C
High Performance Resonant
Mode Controller with
Integrated High-Voltage
Drivers
The NCP1398 is a high performance controller for half bridge LLC
resonant converters. The integrated high voltage gate driver simplifies
layout and reduces external component count. A unique architecture,
which includes a 750 kHz Voltage Controlled Oscillator whose control
mode permits flexibility when an ORing function is required allows
the NCP1398 to deliver everything needed to build a reliable and
rugged resonant mode power supply. The NCP1398 provides a suite of
protection features with configurable settings allow optimization in
any application. This includes: auto−recovery and latch−off
over−current protection, brown−out detection, open optocoupler
detection, adjustable soft−start and dead−time.
Features
• High−Frequency Operation from 50 kHz up to 750 kHz
• Adjustable Minimum Switching Frequency with ± 3% Accuracy
• Adjustable Dead−Time
• Startup Sequence Via an Externally Adjustable Soft−Start
• Precise and High Impedance Brown−Out Protection
• Latched Input for Severe Fault Conditions, e.g. Over Temperature or
OVP
• Timer−Based Auto−Recovery Overcurrent Protection
• Latched Output Short−Circuit Protection
• Open Feedback Loop Protection for NCP1398B Version
• Disable Input for ON/OFF Control
• Skip Mode with Adjustable Hysteresis
• V_CC Operation up to 20 V
• 1 A / 0.5 A Peak Current Sink / Source Drive Capability
• Common Collector Optocoupler Connection for Easier ORing
• Internal Temperature Shutdown
• Designed with Pin−to−Adjacent−Pin Short Testing Safety
Considerations
• Designed with Open Pin Testing Safety Considerations
• These Devices are Pb−Free and Halogen Free/BFR Free
Typical Applications
• Flat panel Display Power Converters
• High Power AC/DC Adapters
• Computing Power Supplies
• Industrial and Medical Power Sources
• Offline Battery Chargers
