产品概述 返回TOPbqi嘉泰姆
CXSU63149系列是PWM,PWM/PFM自动切换/手动切换控制多用途升压型DC/DC转换控制器。不管使用哪种负载电容，输出都能保持稳定。在使用低ESR电容的时候，需要使用一个0.1Ω的RSENSE用作相位补偿。这使得使用陶瓷电容更简单并且降低了输出的纹波,减小了PCB板的使用面积。也可以使用钽电容和电解电容，这种情况下，不需要使用RSENSE。在内部设有0.9V基准电压，因此使用外接分压电阻就可以在1.5V到30V之间自由设定输出电压。开关频率高达300kHz和180kHz，可减小外部器件的尺寸。作为客户定制产品，也有100kHz和500kHz振荡频率的产品可供选择。</span>CXSU63149系列是PWM控制型。在IC内部有一个限流电路(除500kHz版本)并且在监测FB端子的纹波电压，当纹波电压超过250mV就停止工作。复位CE端子或重新上电就能使IC恢复工作。The CXSU63147/CXSU63148/CXSU63149 series are PWM, PWM/PFM auto switching /manual switching controlled universal step-up
DC/DC converter controllers.
Output will be stable no matter which load capacitors are used but should a low ESR capacitor be used, RSENSE of about 0.1Ω
will be required and phase compensation will be achieved. This allows the use of ceramic capacitors and enables to obtain lower
output ripple and small PCB design. Tantalum and electrolytic capacitors can also be used, in which case, RSENSE becomes
unnecessary.
With 0.9V internal voltage reference and by using externally connected two resistors, output voltage can be set freely within a
range of 1.5V to 30V. The series is available in 300 kHz and 180 kHz frequencies, the size of the external components can be
reduced. 100 kHz and 500 kHz are also available in custom options.
The CXSU63147 offers PWM operation. The CXSU63148 offers PWM/PFM automatic switching operation. The PWM operation is shifted to
the PFM operation automatically at light load so that it maintains high efficiency over a wide range of load currents. The CXSU63149
offers both PWM and PWM/PFM auto switching operations and it can be selected by external signal.
A current limiter circuit is built-in to the IC (except with the 500 kHz version) and monitors the ripple voltage on the FB pin.
Operation is shut down when the ripple voltage is more than 250mV. The operations of the IC can be returned to normal with
a toggle of the CE pin or by turning the power supply back on.bqi嘉泰姆
