onsemi NCP4328
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. 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.| Part No. | NCP4328 |
