BM1Q104FJ-E2集成電路（IC）的ACDC轉(zhuǎn)換器離線開關(guān)規(guī)格書PDF中文資料

BM1Q104FJ-E2屬于集成電路（IC）的ACDC轉(zhuǎn)換器離線開關(guān)。由羅姆半導(dǎo)體集團(tuán)制造生產(chǎn)的BM1Q104FJ-E2AC DC 轉(zhuǎn)換器，離線開關(guān)該系列是元器件級控制產(chǎn)品，用于構(gòu)建將交流市電轉(zhuǎn)換為直流電（通常電壓大幅降低）的設(shè)備。集成和未集成系統(tǒng)主要開關(guān)元件的器件均包括在內(nèi)。由于高輸入輸出電壓比，以及此類系統(tǒng)中通常需要隔離，這些器件通常與外部變壓器配合使用。盡管通常使用定制變壓器來實現(xiàn)此用途，但也有許多專門用于此用途的庫存產(chǎn)品，請參見“開關(guān)轉(zhuǎn)換器，SMPS 變壓器”標(biāo)題。

General

The quasi-resonant controller typed AC/DC converter IC

“BM1Q104FJ provides an optimum system for all

products that include an electrical outlet. The

quasi-resonant operation enables soft switching and

helps to keep EMI low. As MOSFET for switching and

current detection resistors are external devices, a higher

degree of design freedom is achieved.

IC builds in HV starter circuit that tolerates high voltage,

it contributes to low consumption power and high speed

start. Because IC consumption current is very low and

burst operation in light load, the stand-by power is very

low.

IC controls to switch bottom numbers in response to

loads. And IC builds in harsh sound prevention function of

transformer in burst operation.

Because IC builds-in soft-start, burst mode, over current

limiter which is cycle-by-cycle, over load protection, over

voltage protection, CS open protection and so on, IC

provides safety.
