NCP4328
Secondary Side CV/CC
Controller
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 TSOP−5 package while the
NCP4328B is available in TSOP−6 package. www.onsemi.com MARKING
