Description
| 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 |
| 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 to pole output ideally suited for driving a power MOSFET. Protection circuitry includes built in under-voltage lockout and current limiting. |
