Not Recommended for New Designs. Refer to MP2147.The MP38115DQ-LF-Z is an internally compensated 1.5MHz fixed frequency PWM synchronous step-down regulator. MP38115DQ-LF-Z operates from a 1.1V to 5.5V input and generates an output voltage as low as 0.8V. The MP38115DQ-LF-Z integrates a 60mΩ high side switch and a 60mΩ synchronous rectifier for high efficiency without an external Schottky diode. With peak current mode control and internal compensation, the MP38115DQ-LF-Z based solution delivers a very compact footprint with a minimum component count. The MP38115DQ-LF-Z is available in a small 3x3mm 10-lead QFN package. 9icnet Electronics is an authorized Monolithic Power Systems distributor.
