DC6M4/5/6 series
6 MHz DC/DC
step-down converter
Small, highly efficient switching converters
with ultra-low output voltage ripple
Ideal`for`mobile`and`battery`driven`devices,`the`DC6M4/5/6`series`combine`the`advantages`of`a`high`
frequency`DC/DC`buck`converter`with`high`performance`and`small`package`(1.0`mm`*`1.4`mm).`The`
6`MHz`switching`frequency`allows`use`of`inductors`as`small`as`470`nH`to`save`board`space.`Another`
key`advantage`is`the`ultra-low`output`voltage`ripple`performance`of`only`7`mV`(typ).
Key features

`
` Input`voltage`range`2.3`V`-`5.5`V
`
` Available`with`output`currents`of`425,`500,`650`mA
`
` Low`quiescent`current`of`0.2`µA`(typ)`in`shutdown
`
` Inrush,`short`circuit`&`temperature`protection
`
` Available`with`Auto/PWM`mode`select,`output`voltage``
select`or`power`good/XSHUTDOWN`option
