目录7.相关产品 产品概述 返回TOP CXUS65123 CXUS65124是升压型的电荷泵IC系列，外部仅使用两个电容就能够得到高效,稳定的正电压输出。输出电压可以在2.5V～6.0V范围内以0.1V为间隔自由选择。通过调节电荷泵的输出阻抗可以得到稳定的输出，以及降低纹波。轻负载条件时工作切换到PFM(脉冲跳跃)控制方式而不会影响输出阻抗和纹波，可以防止效率降低。低功耗以及高效率的特点，使得该系列适用于所有电池类驱动的产品中的应用。The CXUS65123 CXUS65124 series are fixed regulated voltage step-up charge pump ICs which provide stable, highly efficient, positive voltages with the only external components required being 2 capacitors. Since regulating is done via the control of the charge pump's gate voltage waveform, ripple is minimal. Output voltage is selectable in 100mV steps within a 2.5V ~ 6.0V range. Control of the CXUS65124 switches to PFM (pulse skip) during light loads without affecting output impedance or ripple so that the IC is protected against drops in efficiency. Connecting the SENSE pin to the GND pin allows the IC to be used as a voltage doubler. As well as the ultra small MSOP-8A and USP-8 packages, the small consumption current and high efficiencies of the series make the CXUS65123 CXUS65124 suitable for use with all types of battery operated applications. 产品特点 返回TOP
