Analog Devices Inc. Power Supply Reference Designs offer a wide portfolio of options. The MAXREFDES7 uses an H-bridge transformer driver and a pair of low dropout linear regulators to create a ±12V (±15V) output isolated power supply from a 3.3V voltage input. The MAXREFDES8 uses an H-bridge transformer driver and a low dropout linear regulator to create a 12V (15V) output isolated power supply from a 3.3V voltage input. The MAXREFDES9 uses a step-up controller, a 36V H-bridge transformer driver, and a pair of low dropout linear regulators to create a ±15V (±12V) output isolated power supply from a wide range of input voltages. The MAXREFDES33 is a demonstration board for the MAX15062A 60V, 300mA synchronous step-down converter.
