SC2542TETRT規(guī)格書(shū)詳情

SC2542TETRT屬于集成電路(IC)的PMIC-穩(wěn)壓器-DCDC開(kāi)關(guān)式控制器。由Semtech Corporation制造生產(chǎn)的SC2542TETRTDC-DC 開(kāi)關(guān)控制器PMIC(電源管理集成電路)DC 到 DC 開(kāi)關(guān)式控制器是用于高效率電路的穩(wěn)壓 IC,其配置為生成高于(突升或步升)或低于(突降或步降)輸入電源的輸出電源電壓。其他拓?fù)浣Y(jié)構(gòu)可能包括:降壓-升壓、反激、正激、Cuk、SEPIC、全橋、半橋和推挽式。這些器件不同于需要最小電壓并“燒盡”多余電壓的線性穩(wěn)壓器。

Description

SC2542 is a high performance dual PWM controller. It is designed to convert a widely ranged battery rail down to two independent output rails. The PWM operation of the two channels are 180 degrees out of phase which can greatly reduce the size and the cost of the input capacitors. Synchronous buck PWM topology and voltage mode control allow fast transient response and flexible component selection for easy designs. A 5V standby regulator is integrated. A 10V internal linear regulator provides the bias for the controller, and this voltage is optimized for gate drivers to deliver high efficiency.

Features

◆ Independent dual-switcher-outputs

◆ Integrated 5V standby output with over 50mA capability

◆ Wide input voltage range: 6.5V ~ 28V

◆ Adjustable output voltage down to 0.75V

◆ Light load efficiency enhancement

◆ Programmable skip mode operation

◆ Flexible power sequencing with enable and power good output

◆ Synchronous buck topology with voltage mode control

◆ Out of phase operation to reduce cost of input capacitor

◆ 10V internal regulator for gate driver to deliver high efficiency

◆ Programmable switching frequency: 100KHz ~ 300KHz

◆ Full protection: UVLO, OVP, and programmable OCP

◆ No need for current sense resistor

◆ Low standby operating current (200μA typical)

◆ Low shut down current (100nA typical)

◆ 28 lead TSSOP package with exposed die pad (EDP)

◆ Fully WEEE package and RoHS Compliant

Applications

◆ Notebook computer system power

◆ Systems with 6.5V ~ 28V input

◆ Network and telecom systems

◆ Other portable devices
