SOP-14LSummary:
CX9428 chip is a current mode boost chip with a fixed frequency of 600KHz, high efficiency, and wide input range, and has high efficiency synchronous boost function and adjustable current limiting function.
CX9428 chip is specially designed with a voltage protection system to prevent load short circuits from causing system bus burnout or damage. The power supply chip has the characteristics of a current limiting switch transistor drive and a synchronous rectifier switch transistor drive internally to achieve low power consumption and high efficiency power switching. Users can flexibly establish dynamic loops through external compensation to achieve optimal transient performance under all conditions.
CX9428 chip also includes undervoltage latch, overcurrent protection, and over temperature protection to prevent damage in the event of output overload.
