POWER LOSS (mW) LTM8020 200mA, 36V DC/DC Module Regulator FEATURES DESCRIPTION n Complete Step-Down Switch Mode Power Supply The LTM 8020 is a complete 200mA, DC/DC step-down n Wide Input Voltage Range: 4V to 36V power supply. Included in the package are the switch- n 1.25V to 5V Output Voltage ing controller, power switches, inductor, and all support n EN55022 Class B Compliant components. Operating over an input voltage range of 4V n 200mA Output Current to 36V, the LTM8020 supports an output voltage range of n Current Mode Control 1.25V to 5V, set by a single resistor. Only bulk capacitors n 55C to 125C Operating Temperature are needed to finish the design. The LTM8020 meets the (LTM8020MPV) radiated emissions requirements of EN55022. Conducted n Pb-Free (e4) RoHS Compliant Package with Gold Pad emission requirements can be met by adding standard Finish filter components. n Tiny, Low Profile (6.25mm 6.25mm 2.32mm) The low profile (2.32mm) tiny package enables utilization Surface Mount LGA Package of unused space on the bottom of PC boards for high density point of load regulation. APPLICATIONS The LTM8020 is packaged in a thermally enhanced, compact (6.25mm 6.25mm) and low profile (2.32mm) n Automotive Battery Regulation over-molded land grid array (LGA) package suitable for n Power for Portable Products automated assembly by standard surface mount equip- n Distributed Supply Regulation ment. The LTM8020 is Pb-free and RoHS compliant. n Industrial Supplies L, LT, LTC, LTM, Module, Linear Technology, the Linear logo and Burst Mode are registered n Wall Transformer Regulation trademarks of Analog Devices, Inc.
