SC2545TSTRT屬于集成電路(IC)的PMIC-穩(wěn)壓器-DCDC開關(guān)式控制器。由Semtech Corporation制造生產(chǎn)的SC2545TSTRTDC-DC 開關(guān)控制器PMIC(電源管理集成電路)DC 到 DC 開關(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
The SC2545 is a high performance dual PWM controller. It is designed to convert a wide ranged input voltage down to two independent output rails. The SC2545 support “peel off ” tracking for the two outputs at start up which means the two outputs ramp up together till the one with lower output level reaching the regulation. The PWM operations of the two channels are 180 degree 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 high efficiency operation, fast transient responses, and flexible component selection for easy designs.
Features
◆ Independent dual-outputs
◆ “Peel off “start up trackingIndependent dual-outputs
◆ Wide input voltage range: 4.5V~28V
◆ Adjustable output voltage down to 0.75V
◆ 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 shutdown current (100nA typical)
◆ 24 lead TSSOP and MLPQ packages
◆ Fully WEEE and RoHS Compliant
Applications
◆ Systems with 4.5V~28V input
◆ LCDTV and PDPTV
◆ Network and telecom systems
