Description
General part information
LT8580 Series
The LT8580 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 running or synchronized, and can be set between 200kHz and 1.5MHz.The LT8580 also features innovativeSHDNpin circuitry that allows for slowly varying input signals and an adjustable undervoltage lockout function.Additional features such as frequency foldback and soft-start are integrated. The LT8580 is available in tiny thermally enhanced 3mm × 3mm 8-lead DFN and 8-lead MSOP packages.APPLICATIONSVFD Bias SuppliesTFT-LCD Bias SuppliesGPS ReceiversDSL ModemsLocal Power Supply
