High voltage large-current high efficiency synchronous boost chip ZCC9429
a product review
ZCC9429 is a chip having a fixed frequency of 600KHz, high efficiency, wide input current range mode step (the BOOST) chip, and has a high efficiency synchronous boost and adjustable current limiting. The switching power boost BOOST voltage protection system specially designed to prevent the short-circuit load or cause damage to the system bus blown. The chip power supply having a current limiting switch and driving a synchronous rectifier switch driving characteristics, for low power, high efficiency switching power supply. The user may flexibly create dynamic external loop compensation to obtain optimal transient performance under all conditions. ZCC9429 chip also includes undervoltage lockout, overcurrent protection and overtemperature protection, to prevent damage when the output is overloaded.
