AN30180A

DReovcisNioon. . T5A4-EA-06078 Product Standards AN30180A VIN = 2.5V to 5.5V 1.2A Synchronous DC-DC Step Down Regulator FEATURES DESCRIPTION  Wide output voltage range : 1.15V to 2.80V  Input voltage range : 2.5V to 5.5V  Up to 1200mA Output Current  Load transient response is fast  Output current limit control of 1.8A to prevent Excessive current flows  High efficiency over a wide load current area by DCM (discontinuous conductive mode) operation at light loads, CCM (continuous conductive mode) operation in heavy loads those two modes can be automatically switched  Switching frequency of 2.6MHz during CCM.  100% duty operation when input voltage goes down to output voltage.  9 pin Wafer level chip size package (WLCSP Type) Size : 1.46  1.46 mm ( 0.5 mm pitch) AN30180A is a synchronous DC-DC Step Down Regulator and employs the hysteretic control system. By this system, when load current charges suddenly, it responds at high speed and minimizes the c...
