Features & Applications

The SG3525AN is a 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 be slaved or a single unit to be synchronized to an external system clock. A single resistor between the CT and the discharge terminals provide a wide range of dead time ad- justment. These devices also feature built-in soft-start circuitry with only an external timing capacitor required. A shutdown terminal controls both the soft-start circuity 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.

Features:

  • 8 TO 35 V Operation
  • 5.1 V Reference Trimmed to ± 1 %
  • 100 Hz TO 500 KHz Oscillator Range
  • Seperate Oscillator Sync Terminal
  • Adjustable Deadtime Control
  • Internal Soft-Start
  • PUulse-By-Pulse Shutdown
  • Input undervoltage Lockout With Hystersis
  • latching PWM to Prevent Multiple PULSES
  • DUAL Source/Sink Output Drivers
