MICREL SEMICONDUCTOR MIC38C43YM 芯片, 脉宽调制控制器, 电流模式, 7.6-20V, SOIC-8
General Description
The MIC38C4x are fixed frequency, high performance, current-mode PWM controllers. ’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 UC3842/3843/3844/3845A
• Trimmed oscillator discharge current
• UVLO with hysteresis
• Low cross-conduction currents
