UC3637NTI的开关模式控制器全新原装现货供应，欢迎选购 产品信息特性 Single or Dual Supply Operation±2.5V to ±20V Input Supply Range±5% Initial Oscillator Accuracy; ±10% Over TemperaturePulse-by-Pulse Current LimitingUnder-Voltage LockoutShutdown Input with Temperature Compensated 2.5V ThresholdUncommitted PWM Comparators for Design FlexibilityDual 100mA, Source/Sink Output Drivers 说明 The UC1637 is a pulse width modulator circuit intended to be used for a variety of PWM motor drive and amplifier applications requiring either uni-directional or bi-directional drive circuits. When used to replace conventional drivers, this circuit can increase efficiency and reduce component costs for many applications. All necessary circuitry is included to generate an analog error signal and modulate two bi-directional pulse train outputs in proportion to the error signal magnitude and polarity.This monolithic device contains a sawtooth oscillator, error amplifier, and two PWM comparators with ±100mA output stages as standard features. Protection circuitry includes under-voltage lockout, pulse-by-pulse current limiting, and a shutdown port with a 2.  陈伟雄 (销售部经理)电　　话：86 755 83643855移动电话：13590164498传　　真：86 755 83643855地　　址：中国广东 深圳市福田区 华强电子世界三号楼二楼2A207邮　　编：518000公司主页：http://www.htd-ic.com/
