FSL336LRN屬于集成電路（IC）的ACDC轉(zhuǎn)換器離線開(kāi)關(guān)。由安森美半導(dǎo)體公司制造生產(chǎn)的FSL336LRNAC DC 轉(zhuǎn)換器，離線開(kāi)關(guān)該系列是元器件級(jí)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(kāi)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(lèi)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(lái)實(shí)現(xiàn)此用途，但也有許多專(zhuān)門(mén)用于此用途的庫(kù)存產(chǎn)品，請(qǐng)參見(jiàn)“開(kāi)關(guān)轉(zhuǎn)換器，SMPS 變壓器”標(biāo)題。

Description

The FSL336LR integrated Pulse Width Modulator (PWM) and

SENSEFET? is specifically designed for high?performance offline

buck, buck?boost, and non?isolation flyback Switched Mode Power

Supplies (SMPS) with minimal external components. This device

integrates a high?voltage power regulator that enables operation

without auxiliary bias winding. An internal transconductance amplifier

reduces external components for the feedback compensation circuit.

The integrated PWM controller includes: 10 V regulator for no

external bias circuit, Under?Voltage Lockout (UVLO), Leading?Edge

Blanking (LEB), an optimized gate turn?on / turn?off driver, EMI

attenuator, Thermal Shutdown (TSD), temperature?compensated

precision current sources for loop compensation, and fault?protection

circuitry. Protections include: Overload Protection (OLP),

Over?Voltage Protection (OVP), and Feedback Open Loop Protection

(FB_OLP). FSL336LR offers good soft?start performance during

startup.

The internal high?voltage startup switch and the Burst?Mode

operation with very low operating current reduce the power loss in

Standby Mode. As the result, it is possible to reach power loss of

120 mW without external bias and 25 mW with external bias when

input voltage is 230 VAC.
