        1A 1.5MHz降壓轉換器--AT7170/AT7170E

        亚投彩神分類: 穩壓管 LDO
          The AT7170/AT7170E is a high-efficiency,DC-to-DC step-down switching regulator, capable of delivering up to 1A of output current. The devices operate from an input voltage range of 2.6V to 5.5V and provide output voltages from 0.6V to VIN,making the AT7170/AT7170E ideal for low voltage power conversions.

          4.5V-18V輸入,2A同步整流降壓轉換器--AP2972C
          4.5V-18V輸入,2A同步整流降壓轉換器--AP2972C
          AP2972是一款簡單、便于應用的效率高同步降壓轉換器,它采用 SOT-23-6L封裝提供2A負載電流。 AP2972工作于很寬的輸入電壓范圍 (4.5V-18V),內部集成非常低導通電阻的主開關管和同步開關管以減少傳導損耗。AP2972采用COT架構可以在大負載跌落應用中實現瞬態響應和輕負載時的效率。此外,在重負載下的工作頻率為 500 kHz以減小電感和電容的尺寸。故障保護包括周期電流限制,輸出欠 電壓保護,輸出過流保護,輸出短路保護以及熱關斷。

          Dual 1A 1.5MHz同步降壓轉換器--AT7172
          The AT7172 is a dual high-efficiency Pulse-Width Modulated(PWM) step-down DC-DC converter. It is capable of delivering 1A output current over a wide input voltage range from 2.6V to 5.5V, the AT7172 is ideally suited for portable electronic devices that are powered from 1-cell Li-ion battery or from other power sources within the range such as cellular phones, PDAs and other handheld devices.

                      1A 1.5MHz降壓轉換器--AT7170/AT7170E

            一 概述 

            The AT7170/AT7170E is a high-efficiency,DC-to-DC step-down switching regulator, capable of delivering up to 1A of output current. The devices operate from an input voltage range of 2.6V to 5.5V and provide output voltages from 0.6V to VIN,making the AT7170/AT7170E ideal for low voltage power conversions. Running at a fixed frequency of 1.5MHz allows the use of small inductance value and low DCR inductors, thereby achieving higher efficiencies. Other external components, such as ceramic input and output caps, can also be small due to higher switching frequency, while maintaining exceptional low noise output voltages. Built-in EMI reduction circuitry makes this converter ideal power supply for RF applications. Internal soft-start control circuitry reduces inrush current. Short-circuit and thermal-overload protection improves design reliability.
            AT7170/AT7170E is housed in a tiny SOT25 &TDFN2×2-6L package.
