Description
The CS384XB provides all the necessary
Features
- to implement off-line fixed frequency current-mode control with a minimum number of external components. The family has been optimized for very low start up current (300µA, typ). The CS384XB family incorporates a precision temperature-controlled oscillator with an internally trimmed discharge current to minimize variations in frequency. A precision duty-cycle clamp eliminates the need for an external oscillator when a 50% duty-cycle is used. Duty-cycles of almost 100% are possible. On board logi.
