NJW1616-T
600mA, 500kHz, Step-Down Switching Regulator
in SOT-23
GENERAL DESCRIPTION
The NJW1616 is a switching regulator IC for buck converter that
operates wide input voltage range from 4.5V to 20V. The wide input
range makes the NJW1616 suitable for several applications such as
12V commodity supplies, and the other unregulated voltage sources.
It corresponds to Low ESR output capacitor (MLCC), high
operating frequency of 500kHz, internally compensated and small
SOT-23 package. Therefore, the NJW1616 can realize downsizing of
applications with a few and tiny external parts so that adopts current
mode control.
Also, it has a soft start function, over current protection and thermal
shutdown circuit.
