Texas Instruments (LM3674MF-1.2/NOPB)Buck (Step Down) Switching Regulator

Buck (Step Down) Switching Regulator, Fixed, 2.7V-5.5V In, 1.2V And 0.6A Out,SOT-23-5Product OverviewThe LM3674MF-1.2/NOPB is a step-down DC-to-DC Converter optimized for poweringlow-voltage circuits from a single Li-ion cell battery and input voltage railsfrom 2.7 to 5.5V. It provides up to 600mA load current over the entire inputvoltage range. There are several fixed output voltages and adjustable outputvoltage versions. The device offers superior features and performance for mobilephones and similar portable systems. During the pulse width modulation (PWM)mode, the device operates at a fixed-frequency of 2MHz (typical). Internalsynchronous rectification provides high efficiency during the PWM modeoperation. In shutdown mode, the device turns off and reduces batteryconsumption to 0.01��A (typical). During the first portion of each switchingcycle, the control block in the LM3674 turns on the internal PFET switch. Thisallows current to flow from the input through the inductor to the output filtercapacitor and load.Operates from a single li-ion cell batteryInternal synchronous rectification for high efficiencyInternal soft-startCurrent overload protection and thermal shutdown protectionGreen product and no Sb/BrApplicationsCommunications & Networking, Power Management, Portable Devices, Audio,Computers & Computer PeripheralsProduct InformationTopology: Buck (Step Down)Input Voltage Min: 2.7VInput Voltage Max: 5.5VDC / DC Converter IC Case: SOT-23No. of Pins: 5PinsOutput Current: 600mAOutput Voltage Nom: 1.2VSwitching Frequency: 2MHzOperating Temperature Max: 85��CMSL: MSL 1 - Unlimited
