Description
NN3471FAS-A is a synchronous DC-DC step down regulator (1-ch), Power Supply in Package (PSiP), which integrates a Controller IC that employs a hysteretic control system, two Power MOSFETs, an Inductor and Capacitors into a single 8.5 x 7.5 x 4.7mm QFN package. The easiness of mounting PSiP onto a Printed Circuit Board (PCB), a very small footprint and a highly reduced number of external components, offers very compact and simplified solutions for applications requiring point-of-load design.
