| Market Reality | The SG3525A is the voltage-mode PWM controller that runs the push-pull and half-bridge stages of welder inverters, offline inverters, UPS and battery chargers: 8V to 35V operation, a trimmed 5.1V reference, 100Hz to 400kHz, and +/-400mA totem-pole outputs strong enough to drive MOSFET gates without an external driver - the exact reason welder designers chose it over the TL494 class. Its identity is a triangle of pin-pure second sources (UC3525 from Unitrode, KA3525A from the Fairchild line), and its standing trap is the SG3524, a first-generation ancestor whose name sits digits away and whose control pins do not map. | The SG3525A is the voltage-mode PWM controller that runs the push-pull and half-bridge stages of welder inverters, offline inverters, UPS and battery chargers: 8V to 35V operation, a trimmed 5.1V reference, 100Hz to 400kHz, and +/-400mA totem-pole outputs strong enough to drive MOSFET gates without an external driver - the exact reason welder designers chose it over the TL494 class.
