  • The NCP4328 is a secondary side SMPS controller designed for use in applications which requires constant current and/or constant current regulation. The NCP4328x consists of two OTA amplifiers for voltage and current loop regulation with precise internal voltage references. Outputs of OTAs are open drain type (OTAs sink current only). The NCP4328B includes a LED driver pin implemented with an open drain MOSFET driven by a 1 kHz square wave with a 12.5% duty cycle working when VCC is above UVLO for indication purpose. The NCP4328A is available in TSOP5 package while the NCP4328B is available in TSOP6 package.
