LM384N - Brand New National Semiconductor Audio Amplifiers
-
Description
The LM384N is an audio amplifier electronic component model that belongs to the category of audio amplifiers. It is a fixed frequency current-mode PWM controller that is extensively used in off-line and DC-to-DC converter applications with minimal external components. The integrated circuits in LM384N come with a trimmed oscillator for precise duty cycle control, a temperature-compensated reference, high-gain error amplifier, current sensing comparator, and a high-current totem pole output ideally suited for driving a power MOSFET. Furthermore, it features protection circuitry that includes a built-in under-voltage lockout and current limiting.
Specifications and features
● Automatic Feed Forward Compensation
