Power Card
The SG3526BDW-TR is a high-performance "count-down" linear voltage regulator controller from MicroSemi's Power Card family. It is used to control multiple outputs of DC/DC converters in step-down, step-up and other power-factor converters. It offers improved power supplies current and voltage accuracy, line harmonics and EMI harmonic suppression as well as improved system efficiency. The part has a wide range of electrical features, including adjustable operating frequency and pulse width modulation ratio, internal and external current sensing, built-in protection mechanisms, and a wide operating voltage range of -25V to +25V. It is offered in a 16-pin dual in-line package and is pplicatble for power supplies up to 600W.
