LTM4622AIV#PBF

直流/直流POL转换器, 可调, 降压, 4 MHz, 3.6 V至20 V输入, 1.5 V至12 V/2 A输出, LGA-25

The from Linear technology is a dual ultrathin 2A or single 4A step-down DC/DC µModule regulator in 25 pin LGA package. It is a complete dual 2A step-down switching mode µModule® regulator in a tiny ultrathin 6.25mm × 6.25mm × 1.82mm LGA package. Included in the package are the switching controller, power FETs, inductor and support components. Operating over an input voltage of 3.6V to 20V, the LTM4622A supports an output voltage of 1.5V to 12V, set by a single external resistor. Its high efficiency design delivers dual 2A continuous, 3A peak output current. Only a few ceramic input and output capacitors are needed. The LTM4622A supports selectable burst mode operation and output voltage tracking for supply rail sequencing. Its high switching frequency and current mode control enable very fast transient response to line and load changes without sacrificing stability. Fault protection features include input overvoltage, output overcurrent and overtemperature protection.
