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 packa.
