STR-W6053S屬于集成電路（IC）的ACDC轉(zhuǎn)換器離線(xiàn)開(kāi)關(guān)。由三墾電氣株式會(huì)社制造生產(chǎn)的STR-W6053SAC DC 轉(zhuǎn)換器，離線(xiàn)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 STR-W605xS series are power ICs for switching power supplies, incorporating a power MOSFET and a current mode PWM controller IC. Including a startup circuit and a standby function in the controller, the product achieves low power consumption, low standby power, and high cost-effectiveness power supply systems with few external components.

Features and Benefits

? TO-220F power package with 30 to 90 W power output

? Current Mode PWM control

? Built-in Random Switching function, reducing EMI noise, and simplifying EMI filters, and therefore reducing cost

? Built-in Slope Compensation function, avoiding subharmonic oscillation

? Built-in Auto Standby function (Input Power, PIN < 30 mW at no load)

? Normal operation: PWM mode

? Light load operation: Standby mode (burst oscillation)

? Built-in Audible Noise Suppression function during Standby mode

? Built-in Startup Circuit, reducing power consumption in standby operation, and eliminating external components.

? Bias-Assist function, improving startup operation, suppressing VCC voltage drop in operation, and allowing use of smaller VCC capacitor

? Built-in Leading Edge Blanking function

? Two-chip structure, with a controller and a power MOSFET with guaranteed avalanche energy available to simplify surge absorber circuits

? Protection functions:

? Brown-In and Brown-Out Protection function: auto-restart, prevention of excess input current and heat rise at low input voltage

? Overcurrent Protection function (OCP): pulse-by-pulse built-in compensation circuit to minimize OCP point variation on AC input voltage

? Overload Protection function (OLP): auto-restart, built-in timer, reduces heat during overload condition, and no external components required

? Overvoltage Protection function (OVP): Auto-restart

? Thermal Shutdown Protection function (TSD): Auto-restart

Applications:

For switching power supplies used in:

? White goods

? Consumer electronics

? Office automation

? Industrial equipment

? Communication equipment
