Description
GM38C4x is fixed frequency, high performance, and current- mode PWM controllers.
Gamma's BiCMOS devices are pin compatible with standard 384x bipolar devices but with several improvements.
Features
- a trimmed oscillator discharge current and bandgap reference. GM38C4x denotes 8-pin plastic DIP and SOP packages. Features
40ns output rise and 30ns output fall times -40° to +85°C temp. range same as standard UC284x Low-power BiCMOS Process Very low start-up current (50µA typical) Low operating current (4mA typical) CMOS outputs with rail-to-rail swing 500kHz current-mode operation Pin-for-pin compatible with UC3842/ 3843 / 3844/ 3845(A) Trimmed oscillator discharge current UVLO with hysteresi.
