Description
GM384XA series is high performance with fixed-frequency current mode PWM controllers.
They are specially designed for off-Line and DC-to-DC converter applications.
They require minimal external components to precisely tailor performance in a wide variety of applications.
GM384XA series includes a trimmed oscillator for precise duty cycle control, a temperature-compensated reference, high gain error amplifier, a current-sensing comparator, and a high-current totem pole output for driving a power MOSFET.
On-chip protection features include undervoltage lockouts with hysteresis for both input and reference, cycle-by-cycle current limiting, programmable output de...
