产品概述 返回TOP
CXSU63143系列是内置高速低通态电阻驱动器的通用升压DC/DC转换控制器集成电路。使用晶体管,线圈,二极管和电容器共4个外置元件，构建高效的升压DC/DC转换器。该器件可在1.5V～6.5V (±2.5％)范围内，以0.1V的间隔进行设定(VOUT型)。并且，除了VOUT型之外，还备有内置1.0V的基准电压源，以外置元件可任意设定输出电压的型号(FB型)。因开关频率高达300kHz，可使用小型外部元件。在小负载时，PWM／PFM切换控制型CXSU63143系列以PFM工作模式进行工作。因此，在从小负载至大输出电流的整个负载范围内，达到高效率。关于软启动时间，有在内部设定为10ms的型号(A,B,E型)，以及可用外置电阻和电容器进行调整的的型号(C,D,F型)。使用待机功能，能够停止工作(CE端"L")，使电流消耗降到0.5μA以下。The CXSU63142/CXSU63143 series are multi-functional step-up DC/DC controllers which provide high efficiency outputs by using an externally connected transistor, coil, diode and capacitor. Output voltage is selectable in 0.1V increments within a range of 1.5V ~ 6.5V (±2.5%). For output voltages outside this range, we recommend FB version, which has a 1.0V internal reference voltage. Using the FB version, the required output voltage can be set-up using 2 external resistors. With a 300kHz oscillation frequency, the size of the external components can be reduced. Control switches from PWM to PFM during light loads with the CXSU63143 (PWM/PFM switchable) and the series is highly efficient from light loads to large output currents. Soft start time of CXSU63142/ CXSU63143A, B, and E series is internally set to 10ms and CXSU63142/68C, D, and F series regulate soft-start time by connecting resistors and capacitors externally. During stand-by (CE pin "Low"), supply current is reduced to less than 0.5μA.
