MIC38C45規(guī)格書詳情
General Description
The MIC38C4x are fixed frequency, high performance, current-mode PWM controllers. Micrel’s BiCMOS devices are pin compatible with 384x bipolar devices but feature several improvements.
Features
? Fast 40ns output rise and 30ns output fall times
? –40°C to +85°C temperature range meets UC284x specifications
? High-performance, low-power BiCMOS Process
? Ultralow start-up current (50μA typical)
? Low operating current (4mA typical)
? CMOS outputs with rail-to-rail swing
? ≥ 500kHz current-mode operation
? Trimmed 5V bandgap reference
? Pin-for-pin compatible with UC3842/3843/3844/3845(A)
? Trimmed oscillator discharge current
? UVLO with hysteresis
? Low cross-conduction currents
