SG3525A Pulse Width Modulation Controller IC – DIP-16 Package
The SG3525A series of pulse width modulator integrated circuits are designed to offer improved performance and lowered external parts count when used in designing all types of switching power supplies. The on-chip + 5.1 V reference is trimmed to ±1 % and the input common-mode range of the error amplifier includes the reference voltage eliminating external resistors. A sync input to the oscillator allows multiple units to slave or a single unit to be synchronized to an external system clock. A single resistor between the CT and the discharge terminals provides a wide range of dead time ad- adjustment. These devices also feature built-in soft-start circuitry with only an external timing capacitor required. Tags, UC3525A, UC3525 PWM controller, SG3525A PWM controller, SG3525 PWM controller, SG3525 Pulse Width Modulation Controller, SG3525ANG, SG3525AP.
