Description
The CS3524A PWM control circuit retains the same versatile architecture of the industry standard CS3524(SG3524) while adding substantial improvements.
The CS3524 is pin-compatible with “non-A” versions, and in most applica tions can be directly interchanged. The CS3524A, however, eliminates many of the design restrictions which had previously required additional external circuitry.
