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. |
