♠ LM46002 3.5-V rau 60-V, 2-A Synchronous Step-Down Voltage Converter
LM46002 regulator yog ib qho yooj yim-rau-siv synchronous kauj ruam-down DC / DC converter muaj peev xwm tsav mus txog 2 A ntawm load tam sim no los ntawm ib tug input voltage xws li 3.5 V rau 60 V. Lub LM46002 muab tshwj xeeb efficiency, tso zis raug thiab poob. -tawm voltage nyob rau hauv ib tug heev me me tov loj.Ib tsev neeg txuas ntxiv muaj nyob rau hauv ntau yam kev xaiv tam sim no thiab 36-V qhov siab tshaj plaws input voltage nyob rau hauv tus pin-to-pin tshaj tej pob khoom, xws li LM46001, LM46000, LM43603, LM43602, LM43601 thiab LM43600.Peak-currentmode tswj yog ua haujlwm los ua kom tau yooj yim controlloop them nyiaj thiab lub voj voog-los ntawm-lub voj voog tam sim no txwv.Yeem nta xws li programmable switching zaus, synchronization, lub hwj chim-zoo chij, precision enable, sab hauv soft start, expandable soft start, thiab nrhiav tau ib tug saj zawg zog thiab yooj yim-touse platform rau ntau yam kev siv.Discontinuous conduction thiab tsis siv neeg zaus txo ntawm lub teeb loads txhim kho lub teeb load efficiency.Tsev neeg yuav tsum muaj ob peb yam sab nraud.Pin kev npaj tso cai yooj yim, zoo tshaj PCB layout.Cov yam ntxwv kev tiv thaiv muaj xws li thermal shutdown, VCC undervoltage lockout, lub voj voog-los ntawm-lub voj voog tam sim no txwv, thiab kev tiv thaiv luv luv.LM46002 ntaus ntawv muaj nyob rau hauv 16-lead HTSSOP / PWP pob (6.6 hli × 5.1 hli × 1.2 hli) nrog 0.65-mm lead suab.
