Tle6389-2g V50's unique pwm/pfm control scheme has a duty cycle of up to 100%, forming a very low differential pressure - keshijin mall

TLE6389 Step down DC - The DC switch controller is in 1mA To 2.5A High efficiency in the load range .. This control scheme eliminates the minimum load requirement , Reduce the power supply current under light load to 120μA, The specific value depends on the size of external components . Besides , Adjustable version TLE6389-2GV It can be turned off by enabling the pin , Reduce the input current to 2μA following .TLE6389 The step-down controller drives the external P passageway MOSFET, Support flexible design with output power up to 12.5W Application . Operation in high switching frequency and continuous conduction mode allows the use of small surface mount inductors . At the same time, the requirements for output capacitor are reduced , Maximum program reduction PC Board area and system cost . The output voltage is preset to 5V（TLE6389-2GV50 and TLE6389-3GV50）,TLE6389-2GV The output voltage is adjustable .TLE6389-2GV50 The model has a reset range , Threshold at 4.5V and 4.8V Between , The typical values included are 50mV Small hysteresis . stay TLE6389-3GV50 In the model , The typical value of device reset function hysteresis is 1V. all TLE6389 The output voltage can reach 60V.
