1A, 1.5MHz, 65V Boost/Inverter DC/DC Converter
MILPITAS, CA - September 15, 2014 - Linear Technology Corporation announces the LT8580, a current mode, fixed frequency step-up DC/DC converter with an internal 1A, 65V switch. It operates from an input voltage range of 2.55V to 40V, making it suitable for applications with input sources ranging from a single-cell Li-Ion to automotive inputs. The LT8580 can be configured as either a boost, SEPIC or an inverting converter. Its switching frequency can be programmed, via a single resistor or synchronized to an external clock, between 200kHz and 1.5MHz, minimizing external component sizes. The combination of a 3mm x 3mm DFN package (or MSOP-8E) and tiny externals ensures a very compact footprint while reducing solution cost.
The LT8580's low VCESAT switch, 0.4V at 0.75A, delivers efficiencies of up to 86%. Undervoltage lockout (UVLO) is user adjustable for optimal system performance. A single feedback resistor sets the output voltage, minimizing external components. Other features include external synchronization capability, internal soft-start and thermal shutdown protection.
The LT8580EDD is available in a 3mm x 3mm DFN-8 package and the LT8580EMS8E is offered in a thermally enhanced MSOP-8 package. Pricing starts at $2.35 each for 1,000 piece quantities. Industrial temperature (-40°C to
125°C) versions, the LT8580IDD and the LT8580IMS8E are also available, priced starting at $2.59 each for 1,000 piece quantities. Finally, high temperature (-40°C to 150°C) versions, the LT8580HDD and the LT8580HMS8E, are available, priced starting at $2.84 each for 1,000 piece quantities. All versions are available from stock.
