CS3524A, Voltage Mode PWM Control Circuit with 200mA Output Drivers

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 applications can be directly interchanged.

The CS3524A, however, eliminates many of

CS3524A Features

* an undervoltage lockout circuit which disables all internal circuitry (except the reference) until the input voltage has risen to 8V. This holds standby current low until turnon, and greatly simplifies the design of low power, off-line supplies. The turnon circuit has approximately 600mV of hysteres
