SC2446ITETRT規(guī)格書詳情
SC2446ITETRT屬于集成電路(IC)的特殊用途穩(wěn)壓器。由Semtech Corporation制造生產(chǎn)的SC2446ITETRT特殊用途穩(wěn)壓器該系列產(chǎn)品用于電源控制、某種形式的轉(zhuǎn)換,適用于特定的復(fù)雜應(yīng)用。因此,各種產(chǎn)品特性集差異較大,包括空燃比傳感器接口、汽車交流發(fā)電機(jī)電壓調(diào)節(jié)、DDR 端接、液體透鏡控制、摩托車轉(zhuǎn)向信號(hào)控制、熱電 (peltier) 冷卻器控制、壓電觸覺控制、閥門控制、小型發(fā)動(dòng)機(jī)管理等。
Description
The SC2446 is a high-frequency dual synchronous stepdown switching power supply controller. It provides outof-phase high-current output gate drives to all N-channel MOSFET power stages. The SC2446 operates in synchronous continuous-conduction mode. Both phases are capable of maintaining regulation with sourcing or sinking load currents, making the SC2446 suitable for generating both VDDQ and the tracking VTT for DDR applications.
Features
◆ 2-Phase synchronous continuous conduction mode for high efficiency step-down converters
◆ Out of phase operation for low input current ripples
◆ Output source and sink currents
◆ Fixed frequency peak current-mode control
◆ 75mV/-110mV maximum current sense voltage
◆ Synthesized MOSFET R DS(ON) current-sensing for low-cost applications
◆ Optional resistor current-sensing for precise currentlimit
◆ Dual outputs or 2-phase single output operation
◆ Excellent current sharing between individual phases
◆ Wide input voltage range: 4.7V to 16V
◆ Individual soft-start, overload shutdown and enable
◆ Duty cycle up to 88
◆ 0.5V feedback voltage for low-voltage outputs
◆ External reference input for DDR applications
◆ Buffered V DDQ/2 output
◆ Programmable frequency up to 1 MHz per phase
◆ External synchronization
◆ Industrial temperature range
◆ 28-lead TSSOP - EDP package
Applications
◆ Telecommunication power supplies
◆ DDR memory power supplies
◆ Graphic power supplies
◆ Servers and base stations
