High Performance Resonant Mode Controller with Integrated High-Voltage Drivers

ON Semiconductor 

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

• VCC 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
