The device features a shutdown control, resulting in a

standby current less than 5µA, and an output capable

of driving serial or parallel LED’s. The circuit generates The circuit can start up under full load and operates

The ZXSC310 is offered in the SOT23-5 package which,

when combined with a SOT23 switching transistor,

generates a high efficiency small size circuit solution.
