LMS3655NQRNLRQ1 character

● accords with the AEC-Q100 standard that faces car application

Grade of temperature of parts of an apparatus 1: 40 ° C reachs – + the limits of working environment temperature of 125 ° C

HBM of parts of an apparatus classifies grade 2

CDM of parts of an apparatus classifies grade C6

● has the peak value efficiency of 96% when 12V changeover is 5V

● low EMI and exceed low switch node ringing

10%) of ● 400kHz (± secures switch frequency

● has – 40 ° C comes + the knot lukewarm limits of 150 ° C

● exterior frequency is synchronous

● has in-house filter and 3ms to release the RESET output of clock

● can raise efficient automatic light laden pattern

● cites a base mode of optional and compulsive PWM

Compensation of the buy inside ● , soft start, voltaic limitation, heat closes with UVLO

● has 0.35V to press below 3.5A load when 25 ° C fall (typical cost)

18 μ of ● A IQ_VIN: In 3.3 VOUT and the static electric current that falls without laden circumstance (typical cost)

● outputs voltage: 5V, 3.3V and ADJ (1V comes 20V)

● ± tolerance of 1.5% fiducial voltage

LMS3655NQRNLRQ1 explains

Manostat of LMS3655NQRNLRQ1 synchronous step-down undertook optimizing in the light of high-powered application, can offer the adjustable output of the output voltage of 3.3V or 5V or 1V to 20V. Between PWM and PFM mode without seam changeover and electric current of small static state to be able to ensure come true below all load efficient answer with outstanding transient state.

LMS3655-Q1 of support of circuit of high high speed adjusts the input of 24V the output to 3.3V (400kHz secures frequency) , the abidance that still supports 5.5A at the same time load current. The frequency of innovation is folded return a framework to allow this parts of an apparatus to pass only the inputs voltage adjustment to generate 3.3V output of 3.5V. Input voltage limits can be as high as 36V, transient state tolerance is as high as 42V, conduce to relaxed implementation inputting surge to protect a design.

Output of restoration opening leakage is had inside the filter wave of buy and defer function, can provide correct systematic condition instruction. Depend on this one character, parts of an apparatus need not use add monitoring cell, this saved cost and circuit board space.

LMS3655NQRNLRQ1 parts of an apparatus is electric current of the range of wide input voltage that has in-house compensation function, small static state, high-powered manostat. This parts of an apparatus aims utmost ground reduces end item cost and size, asking to work in slashing car and high-powered industry environment at the same time. Regular job frequency is 400 KHz, allow to use small-sized and passive cell. Sky of this parts of an apparatus carries power comsumption low, need not exterior reserve LDO. Of LMS36x5-Q1 low close electric current and voltage of tall the biggest job to still allow to eliminate exterior and laden switch. To reduce systematic cost further, still offerred advanced restoration to output, this can remove exterior restoration or monitoring parts of an apparatus or appliance normally use.

LMS3655NQRNLRQ1 uses outfit chip or HotRod technology, reduced the parasitism inductance that cites a base greatly. In addition, the layout of this device allows to offset electric current produces unripe magnetic field partly, this reduced the radiation noise that produces by switch movement.

Result, switch node weaveform is shown less rush too and ringing.
