SR036DB1 Inductorless Switching Power Supply
Introduction
The Supertex SR036 is an inductorless, dual output off-line regulator intended for 120/240VAC line operation. The operating principle is to activate a pass element between line and load only when the input voltage is lower than a certain value. Thus conduction only occurs with a low voltage drop across the pass element, resulting in more efficient operation compared to a standard linear regulator. The SR036DB1 demo board contains all the circuitry needed to supply a low-current (<40mA) load. Included are input protection circuitry, a full wave bridge rectifier, a pass element, and output capacitors.
