LM3489QMMX/NOPB character

The car spare parts of ● qualification

AEC-Q100 accords with ● the following result:

1: of equipment temperature grade? C40 ° C works to environment of 125 ° C temperature limits

Equipment HBM ESD classifies grade 2

Equipment CDM ESD classifies grade C5

The control method that ● uses easily

● does not need to control loop compensation

● 4.5 to limits of 35V wide input

● 1.239 V is in to V… in adjustable output limits

● is efficient: 93%

● 1.3% (inside temperature limits 2% ) source of in-house and fiducial voltage

● 100% take sky comparing operation

● is the biggest megahertz of working frequency %3E 1

● current limliting is protected

● is special make can cite a base (the open when joining)

● closes mode to use up 7 A source current only

The 8 VSSOP that cite a base enclose ●

LM3489QMMX/NOPB explains

LM3489QMMX/NOPB is efficient controller of PFET switch adjuster, the price of small-sized, tall sex that can be used at easily development to suit all sorts of application compares switch step-down adjuster. Lag controls a framework to use all sorts of exterior cell, the design is simple, nonexistent problems of any stability of operating ring road. PFET framework still supports small cell number and ultralow pressure difference, 100% take sky comparing operation. Another advantage is what fall in light load is efficient move, and won’t increase output ripple. Special make can bring a foot to offer only of 7 A close mode power comsumption, the acquiesce when making can bring a foot to did not join is.

Current limliting protects the voltage that can go up through measuring PFET resistance to realize DS () , because this does not need,detect resistor. If need, OK use feeling measures resistor to raise current limliting precision. Can adjust with a resistor chase periodic current limliting, ensure inside limits of certain output electric current safety works.
