LT8580 Boost/SEPIC/Inverting DC/DC Converter

The LT®8580 is a PWM DC/DC converter containing an internal 1A, 65V switch. The LT8580 can be configured as either a boost, SEPIC or inverting converter. The LT8580 has an adjustable oscillator, set by a resistor from the RT pin to ground. Additionally, the LT8580 can be synchronized to an external clock. The switching frequency of the part may be free runni.
