SG3525A PWM Controller IC<\/strong> is a versatile 16-pin PWM control IC widely used in switching power supply and power conversion applications. It integrates an oscillator, precision 5.1V reference, error amplifier, PWM comparator, soft-start circuit, shutdown function, undervoltage lockout and dual alternating output drivers.<\/p>\n

The IC is particularly suitable for inverter circuits, SMPS, UPS systems, push-pull converters, half-bridge converters and DC-DC power supplies<\/strong>. Its dual alternating outputs make it convenient for driving external MOSFETs or gate-driver stages in transformer-based switching applications.<\/p>\n
