LT8580

Boost/SEPIC/Inverting

DC/DC Converter with 1A, 65V

Switch, Soft-Start and Synchronization

FEATURES

DESCRIPTION

The LT^®8580 is a PWM DC/DC converter containing an

internal 1A, 65V switch. The LT8580 can be configured

1A, 65V Power Switch

Adjustable Switching Frequency

Single Feedback Resistor Sets V

as either a boost, SEPIC or inverting converter.

OUT

Synchronizable to External Clock

High Gain SHDN Pin Accepts Slowly Varying

Input Signals

The LT8580 has an adjustable oscillator, set by a resistor

fromtheRTpintoground. Additionally, theLT8580canbe

synchronizedtoanexternalclock.Theswitchingfrequency

of the part may be free running or synchronized, and can

be set between 200kHz and 1.5MHz.

Wide Input Voltage Range: 2.55V to 40V

Low V

Switch: 400mV at 0.75A (Typical)

CESAT

Integrated Soft-Start Function

The LT8580 also features innovative SHDN pin circuitry

that allows for slowly varying input signals and an adjust-

able undervoltage lockout function.

Easily Configurable as a Boost, SEPIC, or Inverting

Converter

User Configurable Undervoltage Lockout (UVLO)

Pin Compatible with LT3580

Tiny Thermally Enhanced 8-Lead 3mm × 3mm DFN

and 8-Lead MSOP Packages

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.
