LM3481QMMX/NOPB character

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

Temperature of parts of an apparatus 1 class: – 40 ° C comes + 125 ° C, TA

The 10 VSSOP that cite a base enclose ●

● has the in-house push-pull drive of ability of electric current of 1A peak value

● electric current is restricted to be worth and be heated up close

● passes the frequency compensation that capacitor and resistor optimize

● interior is soft start

Mode of ● electric current moves

What ● has delay is adjustable owe press a lock to decide

The pulse below condition of ● light load is bouncing

● main norms

2.97V comes the limits of voltage of broad power supply of 48V

100kHz comes of 1MHz adjustable and but limits of synchronous clock frequency

± 1.5% (overheat) in-house and fiducial

10 μ A involves electric current (overheat is protected)

● uses LM3481-Q1 and WEBENCH Power Designer of have the aid of establishs custom-built design

LM3481QMMX/NOPB explains

LM3481QMMX/NOPB is those who apply to switch manostat is muti_function high-powered controller of low side N-FET. Design of this parts of an apparatus is used at step up, SEPIC and the develop that stimulate type converter and need to regard primary switch as low side FET instead to attack. LM3481-Q1 parts of an apparatus can leave the job in very tall switch frequency, use at reducing integral solution size. Through using individual and exterior resistor, or LM3481-Q1 parts of an apparatus and exterior clock synchronism, can adjust the switch frequency of this parts of an apparatus be worth to the random between 1MHz for 100kHz. Besides chasing periodic electric current to restrict, voltaic mode control still can offer outstanding bandwidth and transient state to answer. Can use individual and exterior resistor to be restricted to be worth to electric current undertake process designing.

LM3481QMMX/NOPB parts of an apparatus is had inside buy protects a function, heat up for example close, short circuit is protected and press protection too. Energy-saving close mode to be able to reduce total source current to 5 μ A, support control of power source sequential. The surge electric current when limitation of the soft meeting that start starts interior. Compensation of slope of compositive electric current can simplify design, if specific application needs, can use individual resistor to raise compensation of slope of this electric current.
