Overview of SG3525AN

The SG3525AN is 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 adjustments.

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 the pulsed shutdown, as well as soft-start recycle with longer shutdown commands.

SG3525AN Features

• 8.0 V to 35 V Operation

• 5.1 V 1.0% Trimmed Reference

• 100 Hz to 400 kHz Oscillator Range

• Separate Oscillator Sync Pin

• Adjustable Deadtime Control

• Input Undervoltage Lockout

• Latching PWM to Prevent Multiple Pulses

• Pulse−by−Pulse Shutdown

• Dual Source/Sink Outputs: 400 mA Peak

• Pb−Free Packages are Available*
