ultra high efficiency 94-96% high-speed response step-down dc-dc converter vsv - m3,m6,m8 vsv-m3, m6, m8 is an ultra small size (15244mm size) and light weight (2.6g) step-down dc-dc converter, which has achieved ma ximum 26w. since it can correspond from ultra low output voltage of 1.0v, it can be used for the latest dsp, asic applications. due to hig h-speed response, high efficiency by synchronous rectification circuit technology, saving space by no external components, an excellent performan ce beyond our common sense has been achieved. - latest power-ic adopted - adjustable output - high-speed response - non-isolated type converter - efficiency 94%, 96% - ultra minimum size - on/off control - operating temp. -40c to +85c - heat sink not required - high reliability, high performance - the latest technology, synchronous rectification circuit - additional external capacitor not required - short-circuit, over-current protection - rohs compliance table 1 model rating input voltage no-load input current efficiency package vdc ma(typ.) %(typ.) type vsv-3.3s3r0m 30 96 vsv-3.3s6r0m 60 94 vsv-3.3s8r0m 70 96 note 1: ratin g in p ut volta g e ( ) is the volta g e ran g e, and the in p ut volta g e needs to be 0.5v or more com p ared to the out p ut volta g e. note 2: ratin g out p ut volta g e ( ) is the ad j ustable ran g e. table 2 conditions input voltage/range output voltage accuracy +3.3v3 var pin open. line regulation 0.5% typ. for the regulation of vin=3-5.5 load regulation 1.0% typ. for the regulation of iout=0a-rating temperature coefficient 0.02%/ typ. for the regulation of ta=-40 to 50c adjustable output range refer to table 1 ripple & noise bw=20mh efficiency over-current protection avoid long-time short-circuit condition. over-voltage protection refer to page 3, adjusting voltage setting. no load input current iout=0a remote on/off control between 5pin(rc) 3pin(s.gnd) [open : output on, short : output off] refer to page 4, on/off control. uvlo start up voltage 2.8v typ. uvlo end voltage 2.7v typ. p-good output at normal output : h, at output dropping : l (0-0.4v vin=+5v sinks current=9ma refer to page 4, power good output. or below) operating temp. range operating temp. -40c to +85c refer to page 6, temp. derating. storage temperature range storage temp. -40 to +85c (+125c at baking) humidity range 20%- 95%r.hmax.
