Product Summary

The SG1525AJ is a pulse width modulator integrated circuit designed to offer improved performance and lower external parts count when used to implement all types of switching power supplies. The SG1525AJ on-chip +5.1 volt reference is trimmed to ±1% initial accuracy and the input common-mode range of the error amplifier includes the reference voltage, eliminating external potentiometers and divider resistors. A Sync input to the oscillator allows multiple units to be slaved together, or a single unit to be synchronized to an external system clock.

Parametrics

SG1525AJ absolute maximum ratings: (1)Oscillator Charging Current: 5mA; (2)Operating Junction Temperature Range: 150℃; (3)Storage Temperature Range: -65 to 150℃; (4)Lead Temperature (Soldering, 10 seconds): 300℃; (5)Supply Voltage (+VIN): 40V; (6)Collector Supply Voltage (VC): 40V; (7)Logic Inputs: -0.3 to 5.5V; (8)Analog Inputs: -0.3 to VIN; (9)Output Current, Source or Sink: 500mA; (10)Reference Load Current: 50mA.
