Overview of NCP4328BSNT1G

Meet the NCP4328x, a secondary side SMPS controller designed to provide constant current and/or constant current regulation in various applications. This innovative controller incorporates two OTA amplifiers for voltage and current loop regulation, complete with precise internal voltage references. The open drain type outputs of the OTAs ensure optimal current sinking. Moreover, the NCP4328B variant comes equipped with a LED driver pin featuring an open drain MOSFET driven by a 1 kHz square wave with a 12.5% duty cycle, allowing for indication purposes when VCC is above UVLO. With the NCP4328A available in a TSOP5 package and the NCP4328B in a TSOP6 package, these controllers offer a comprehensive solution for your voltage and current regulation needs
