DESCRIPTION
The LM384xA are fixed frequency current-mode PWM controller. They are specially designed for Off-Line and DC-to-DC converter applications with minimal external components.
These integrated circuits features a trimmed oscillator for precise duty cycle control, a temperature compensated reference, high gain error amplifier, current sensing comparator, and a high current totempole output ideally suited for driving a power MOSFET.
Protection circuitry includes built in under-voltage lockout and current limiting.
FEATURES
● Automatic feed forward compensation
● Optimized for offline converter
● Double pulse suppression
● Current mode operation to 500 KHz
● High gain totem pole output
● Internally trimmed bandgap reference
● Undervoltage lockout with hysteresis
● Low start up current :＜ 0.3 mA
● Moisture Sensitivity Level 3
