GM3844A Datasheet

GM3844A (GM3842A - GM3845A) HIGH PERFORMANCE CURRENT MODE PWM CONTROLLERS

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 tr.

Features

include undervoltage lockouts with hysteresis for both input and reference, cycle-by-cycle current limiting, programmable output deadtime, and a latch for single pulse metering. All these are in a simple DIP-8 or SOP-8 package! GM3842A and GM3844A have UVLO thresholds of 16V (on)/10V(off); GM3843A and GM3845A have UVLO thresholds of 8.4V (on)/ 7.6V (off). GM3842A and GM3843A operate within 100% duty cycle; GM3844A and GM3845A operate within 50% duty cycle. Features Low Start-Up and Operating Current Automatic Feed Forward Compensation Current Mode Operating Frequency up to 500kHz Trimmed Osci.
