Part Number : SG3525AN
Function : REGULATING PULSE WIDTH MODULATORS
Package : DIP 16 Pin
Manufactures : STMicroelectronics
The SG3525Aseries 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 inputcommon-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 betweentheCTandthe dischargeterminals provide a wide range of dead time ad- justment. Thesedevicesalso featurebuilt-insoft-startcircuitry with only an external timing capacitor required.
