LTM8032 EN55022B Compliant 36V, 2A DC/DC Module Regulator Fea T Descrip T n Complete Step-Down Switch Mode Power Supply The LTM 8032 is an electromagnetic compatible (EMC) n Wide Input Voltage Range: 3.6V to 36V 36V, 2A DC/DC step-down Module regulator designed n 2A Output Current to meet the radiated emissions requirements of EN55022. n 0.8V to 10V Output Voltage Conducted emission requirements can be met by adding n Selectable Switching Frequency: 200kHz to 2.4MHz standard filter components. Included in the package are the n EN55022 Class B Compliant switching controller, power switches, inductor, filters and n Current Mode Control all support components. Operating over an input voltage n Programmable Soft-Start range of 3.6V to 36V, the LTM8032 supports an output n SnPb (BGA) or RoHS Compliant (LGA and BGA) voltage range of 0.8V to 10V, and a switching frequency Finish range of 200kHz to 2.4MHz, each set by a single resistor. n Low Profile, Surface Mount LGA (9mm 15mm Only the bulk input and output filter capacitors are needed 2.82mm) and BGA (9mm 15mm 3.42mm) to finish the design. The low profile package enables uti- Packages lization of unused space on the bottom of PC boards for high density point of load regulation. The LTM8032 is packaged in a thermally enhanced, com- a T pact and low profile overmolded land grid array (LGA) and n Automotive Battery Regulation ball grid array (BGA) packages suitable for automated n Power for Portable Products assembly by standard surface mount equipment. The n Distributed Supply Regulation LTM8032 is available with SnPb (BGA) or RoHS compli- n Industrial Supplies ant terminal finish. n Wall Transformer Regulation L, LT, LTC, LTM, Linear Technology, the Linear logo, Module and Burst Mode are registered trademarks of Linear Technology Corporation.
