产品概述 返回TOP
The CXSD62191/CXSD62192/CXSD62193 series is a group of synchronous-rectification type DC/DC converters with a built-in 0.42Ω P-channel MOS driver transistor and 0.52ΩN-channel MOS switching transistor, designed to allow the use of ceramic capacitors. Operating voltage range is from 2.0V to 6.0V (A～C types), 1.8V to 6.0V (D～G types). For the D/F types which have a reference voltage of 0.8V (accuracy: ±2.0%), the output voltage can be set from 0.9V by using two external resistors. The A/B/C/E/G types have a fixed output voltage from 0.8V to 4.0V in increments of 0.05V (accuracy: ±2.0%). The device provides a high efficiency, stable power supply with an output current of 600mA to be configured using only a coil and two capacitors connected externally. With the built-in oscillator, either 1.2MHz or 3.0MHz can be selected for suiting to your particular application. As for operation mode, the CXSD62191 series is PWM control, the CXSD62192 series is automatic PWM/PFM switching control and the CXSD62193 series can be manually switched between the PWM control mode and the automatic PWM/PFM switching control mode, allowing fast response, low ripple and high efficiency over the full range of loads (from light load to heavy load). The soft start and current control functions are internally optimized. During stand-by, all circuits are shutdown to reduce current consumption to as low as 1.0μA or less. The B/F/G types have a high speed soft-start as fast as 0.25ms in typical for quick turn-on. With the built-in UVLO (Under Voltage Lock Out) function, the internal P-channel MOS driver transistor is forced OFF when input voltage becomes 1.4V or lower. The B to G types integrate CL discharge function which enables the electric charge at the output capacitor CL to be discharged via the internal discharge switch located between the LX and VSS pins. When the devices enter stand-by mode, output voltage quickly returns to the VSS level as a result of this function. Four types of package SOT-25, USP-6C, USP-6EL and WLP-5-03 are available
CXSD62193系列是能使用陶瓷电容,内置0.42ΩPch MOS驱动晶体管及0.52ΩNch MOS开关晶体管的同步整流型DC/DC转换器。工作电压范围2.0V～6.0V(A～C系列)，1.8V～6.0V(D～G系列)。由外部设定输出电压的产品(D/F系列)内置0.8V(±2.0%)的基准电压源，由外部电阻可以从0.9V开始设定任意的输出电压。有内部设定输出电压的产品(A/B/C/E/G系列)，其输出电压范围在0.8V～4.0V之间(±2.0%)，能以0.05V的间隔设定。作为外装元件只使用线圈和电容即可得到输出电流600mA的高效率稳定电源。内置1.2MHz,3MHz的振荡器，可根据应用目的选择最佳频率。在内部进行了软启动功能和限流功能的最佳调整。待机时整个电路停止工作能把消耗电流抑制在1.0μA以下。B/F/G系列的软启动功能能以0.25ms(TYP.)高速启动。内置UVLO(Under Voltage Lock Out)功能当输入电压在1.4V以下时，能强制停止内部Pch MOS驱动晶体管工作。此外，B～G系列由CL的放电功能在待机时接通LX-VSS之间的内部开关以通过内部电阻使CL的电荷放电。由此放电功能使得输出电压高速地返回VSS电平。
