Overview
CS3842B/3843B
CS3842B/CS3843B
Off-Line Current Mode PWM Control Circuit with Very Low Start Up Current
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 logic ensures that VREF is stabilized b...
