Image of Analog Devices' LT3580, Boost, SEPIC, Invertering Converter Analog Devices' LT3580 is a PWM DC/DC converter containing an internal 2 A, 42 V switch. This converter can be configured as either a boost, SEPIC, or inverting converter. Capable of generating 12 V at 550 mA or -12 V at 350 mA from a 5 V input. The LT3580 has an adjustable oscillator, set by a resistor from the RT pin to ground. Additionally, this converter can be synchronized to an external clock. The free running or synchronized switching frequency range of the part can be set between 200 kHz and 2.5 MHz. The converter comes in an 8-pin DFN or MSOP package with a wide temperature range up to -55°C to +125°C. The LT3580 is ideal for many local power supply designs.
