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.

http://onsemi.com

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.
