STR3A462HDL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

STR3A462HDL屬于集成電路（IC）的ACDC轉(zhuǎn)換器離線開關(guān)。由三墾電氣株式會社制造生產(chǎn)的STR3A462HDLAC 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。

Description

The STR3A46xHL/HDL series are power ICs for

switching power supplies, incorporating a power

MOSFET and a current mode PWM controller IC.

To enhance efficiency in all load ranges, the IC

automatically shifts its operation to the green mode or

burst oscillation mode, depending on the load. The

product achieves high cost-performance power supply

systems with few external components.

Features

● Bare Lead Frame: Pb-free (RoHS compliant)

● Low Thermal Resistance Package

● Improving circuit efficiency (Since the step drive

control can keep VRM of secondary rectification diodes

low, the circuit efficiency can be improved by low VF)

● Noise Reduction

● Current Mode Type PWM Control

● Soft Start Function

● Automatic Standby Function

No Load Power Consumption < 15mW

● Operation Mode

Normal Operation ----------------------------PWM Mode

Light Load Operation----------------------- Green-Mode

Standby -------------------------- Burst Oscillation Mode

● Random Switching Function

● Slope Compensation Function

● Leading Edge Blanking Function

● Bias Assist Function

● Protections

Two Types of Overcurrent Protection (OCP): Pulseby-Pulse, built-in compensation circuit to minimize

OCP point variation on AC input voltage

Overload Protection (OLP): Auto-restart

Overvoltage Protection (OVP): Auto-restart / Latched
