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: autoârecovery and latchâoff
overâcurrent protection, brownâout detection, open optocoupler
detection, adjustable softâstart and deadâtime.
Features
⢠HighâFrequency Operation from 50 kHz up to 750 kHz
⢠Adjustable Minimum Switching Frequency with ± 3% Accuracy
⢠Adjustable DeadâTime
