WSON (DSK)

10

6 mm 2.5 x 2.5

Features

Input voltage range: 1.8 V to 5.5 V

Output voltage range: 1.8 V to 5 V (100-mV steps)

o Programmable with external resistors

o SEL pin to toggle between two output voltage presets

> 400-mA output current for VI2.0 V, VO = 3.3 V (typical 1.45-A peak switching current limit)

o Stackable: parallel multiple devices for higher output current

> 90% Efficiency at 10-A load current

o 75-nA quiescent current

o 60-nA shutdown current

Single-mode operation

o Eliminates mode transitions between buck, buck-boost and boost operation

o Low output ripple
