SR036 Inductorless, Dual Output Off-Line Regulators ► Accepts peak input voltages up to 700V ► Operates directly off of 120 or 230VAC ► Integrated linear regulator ► Minimal power dissipation ► No high voltage capacitors required ► No transformers or inductors required ► Up to 1.0W output power ► 3.3V power supplies ► SMPS house keeping power supplies ► White goods ► Appliances ► Small off-line low voltage power supplies ► Lighting controls The Supertex SR036 is an inductorless, dual output off-line controller providing up to 1.0W of output power. It does not require any transformers, inductors, or high voltage input capacitors. The input voltage, HVIN, is designed to operate from an full wave 120V or 230V AC line. It is designed to control an external N-channel MOSFET or IGBT. When HVIN is less than 45V, the external transistor is turned-on, allowing it to charge an external capacitor connected to VSOURCE. An unregulated DC voltage will develop on VSOURCE. Once HVIN is above 45V, the transistor is turned off. The maximum gate voltage for the external transistor is 24V. The unregulated voltage is approximately 18V. The SR036 also provides a regulated 3.3V. WARNING! Galvanic isolation is not provided. Dangerous voltages are present when connected to the AC line.
