Description

The CoolSET?-F3(Jitter version) meets the requirements

for Off-Line Battery Adapters and low cost SMPS for the

lower power range. By use of a BiCMOS technology a wide

VCC range up to 26V is provided. This covers the changes

in the auxiliary supply voltage if a CV/CC regulation is

implemented on the secondary side. Furthermore an Active

Burst Mode is integrated to fullfill the lowest Standby Power

Requirements <100mW at no load and Vin = 270VAC. As

during Active Burst Mode the controller is always active

there is an immediate response on load jumps possible

without any black out in the SMPS. In Active Burst Mode

the ripple of the output voltage can be reduced <1.

Furthermore Auto Restart Mode is entered in case of

Overtemperature, VCC Overvoltage, Output Open loop or

Overload and VCC Undervoltage. By means of the internal

precise peak current limitation, the dimension of the

transformer and the secondary diode can be lowered which

leads to more cost efficiency.

ICE3B1565J屬于集成電路（IC） > AC DC 轉(zhuǎn)換器，離線開關(guān)。英飛凌科技股份公司制造生產(chǎn)的ICE3B1565JAC 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(shí)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。
