LM25011MY/NOPBThe LM25011MY/NOPB is a constant on-time non synchronous buck regulator with adjustable current limit in 10 pin MSOP package. This buck regulator features all functions needed to implement a low cost, efficient buck bias regulation. The LM25011 high voltage regulator contains N channel buck switch, startup regulator, current limit detection and internal ripple control. The constant on-time regulation principle requires no loop compensation that results in fast load transient response and simplifies circuit implementation. Operating frequency of device remains constant with line and load. The adjustable valley current limit detection results in a smooth transition from constant voltage to constant current mode when current limit is reached without use of current limit foldback. Additional features include low output ripple, VIN undervoltage lock out, thermal shut down, gate drive precharge, gate drive undervoltage lock out and maximum duty cycle limit., Adjustable output voltage range from 2.51V to 40V, 2A integrated N channel buck switch, Input operating voltage range from 6V to 42V, Switching frequency is 2MHz, Adjustable current limit allows for smaller inductor, Minimum ripple voltage at output, Power good output, Adjustable soft start timing, Precision 2% feedback reference, Operating temperature range -40°C to 125°CМикросхемы / Микросхемы управления питанием / Импульсные преобразователи Корпус: 10-MSOP-EP, инфо: Стаб.напр.импульсный Step-Down 2.0A Uвх=9…42V Uвых=2.51…39V PGood, до 2 МГц, регулир. порог тока
