Power supply. The distinguishing feature of

As Above, So Below is the seventh studio release by American duo Azure Ray, consisting of Maria Taylor and Orenda Fink. It was originally released on September 4, 2012, on Saddle Creek Records and features co-production by Andy LeMaster and Todd Fink. Following a 2-year hiatus after the release of Drawing Down the Moon, Fink and a pregnant Taylor entered the studio to record six news songs, with a more \"hypnotic\" \"electronica\" influence in collaboration with Andy LeMaster and Todd Fink. On July 17, 2012, Stereogum premiered the \"starry, shivering cut\" “Scattered Like Leaves.” NPR premiered \"Red Balloon\" on August 9, 2012, calling the \"long, slow summer swoon,\" \"devastating melancholy.\" Rolling Stone premiered the full EP stream on August 28, 2012.

A push–pull converter is a type of DC-to-DC converter, a switching converter that uses a transformer to change the voltage of a DC power supply. The distinguishing feature of a push-pull converter is that the transformer primary is supplied with current from the input line by pairs of transistors in a symmetrical push-pull circuit. The transistors are alternately switched on and off, periodically reversing the current in the transformer. Therefore, current is drawn from the line during both halves of the switching cycle. This contrasts with buck-boost converters, in which the input current is supplied by a single transistor which is switched on and off, so current is drawn from the line during only a part of the switching cycle. During the remainder of the cycle, the output power is supplied by energy stored in inductors or capacitors in the power supply. Push–pull converters have steadier input current, create less noise on the input line, and are more efficient in higher power applications.
