CJ92910
CJ92910 is 4.5V~100V 1A DC-DC Step-Down Converter manufactured by JCET.
feature makes it ideal for applications that requiring low drop-out voltage. 240μA quiescent current saves the power, and low offcurrent makes it suitable for battery powered applications.
The CJ92910 also has built-in protection features
, such as cycle-by-cycle current limit, hiccup mode short-circuit protection, output over voltage protection, FB open protection and thermal shutdown in case of excessive power dissipation.
The CJ92910 is available in a space-saving ESOP8 package.
