LTM8020 200mA, 36V DC/DC µModule 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 –55°C to 125°C 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, n Automotive Battery Regulation compact (6.25mm × 6.25mm) and low profile (2.32mm) n Power for Portable Products over-molded land grid array (LGA) package suitable for n Distributed Supply Regulation automated assembly by standard surface mount equip- n Industrial Supplies ment. The LTM8020 is Pb-free and RoHS compliant. n L, LT, LTC, LTM, µModule, Linear Technology, the Linear logo and Burst Mode are registered Wall Transformer Regulation trademarks of Analog Devices, Inc.
