CS52843 Features

* to implement off

* line fixed frequency current

* mode control with a minimum number of external components. The CS52843 incorporates a new precision temperature

* controlled oscillator to minimize variations in frequency. An undervoltage lockout ensures that VREF is stabilized bef
