  • Product introduction

ICcontrolTL284xBandTL384xB系列提供necessary的功能的implement离线或直流到直流固定频率Current mode控制方案in order toMinimal external components数目。内部实现电路包括Undervoltage锁定（UVLO）和一个精确的引用，attrim的准确性Error amplifier的输入。其他的内部电路include逻辑，以确保锁定操作，pulsewidthModulation (PWM）的compare，还提供限流控制，以及图腾柱输出leveldevise源或汇的高峰值Current.输出级，DrivenN沟道MOSFETfitlowtime处于关闭状态。

shouldTL284xBandTL384xBseriesof pins与标准TL284xandTL384xand以下改进Compatible.initiatecurrent被指定is 0.5毫安（最大）whereas放电电流振荡修整至8.3 mA（典型值）。此外，在Undervoltage条件下，输出Yes1.2 V的utmost饱和电压，而沉没10 mAh的关系（VCC= 5 V）号。

这些系列的成员之间的主要区别是在UVLO阈值和最大占空比Range. 16五（上）和10 V（关闭）对TLx842Band设备的typicalUVLO的阈值TLx844Benvoy它们非常Suitable for离线应用。forTLx843BandTLx845Bequipment相应的典型阈值是8.4五（上）和7.6五（关闭）。shouldTLx842BandTLx843B设备可以合作，占空比接近100％。 0％至50％占空比scope得到了一个内部触发触发器，whereas空白，Shut down所有其他clockcycle.The TL284xBseries设备的输出Apart from用于操作特点是从composedTLx844BandTLx845B- 40 ° C to85° C的shouldTL384xB系列设备的特点是Work in0 ° C至70° C的
