www.DataSheet4U.com FEATURES n LT3582/ LT3582-5/LT3582-12 I2C Programmable Boo st and Single Inductor Inverting DC/DC Converters with OTP DESCRIPTION The LT 3582/LT3582-5/LT3582-12 are dual DC/DC converters featuring positive and nega tive outputs and integrated feedback re sistors. The LT3582, with its built in One Time Programming (OTP), has config urable output settings via the I2C inte rface, including output voltage setting s, power up sequencing, power down disc harge, and output voltage ramp rates. L T3582 settings can be changed adaptivel y in the final product, or set during manufacturing and made permanent using the built in non-volatile OTP

memory. The positive output voltage can be set between 3.2V and 12.775V in 25mV steps. The negative output voltage can be set between –1.2V and –13.95V i n –50mV steps. The LT3582-5 and LT358 2-12 are pre-configured at the factory for ±5V and ±12V outputs respectivel y. The LT3582 series includes two monol ithic converters, one Boost and one Inv erting. The Boost converter has an inte grated power switch and output disconne ct switch. The Inverting converter uses a single inductor topology and include s an integrated power switch. Both Boos t and Inverting converters use a novel* * control scheme resulting in low outpu t voltage ripple while allowing for hig h conversion efficiency over a wide lo ad current range. The LT3582 series is available in a 16-pin 3mm x 3mm QFN. L, LT, LTC, LTM, Linear Technology and th e Linear logo are registered trademarks of Linear Technology Corporation.
