SG3525A - Pulse Width Modulator Control Circuit

Features

• built.
• in soft.
• start circuitry, requiring only an external timing capacitor. A shutdown pin controls both the soft.
• start circuitry and the output stages, providing instantaneous turn off through the PWM latch with pulsed shutdown, as well as soft.
• start recycle with longer shutdown commands. The under voltage lockout inhibits the outputs and the changing of the soft.
• start capacitor when VCC is below nominal. The output stages are totem.
• pole design ca.
