LTM8032 EN55022B Compliant 36V, 2A DC/DC µModule Regulator
FeaTures DescripTion
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 µModule® 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.
applicaTions
The LTM8032 is packaged in a thermally enhanced, com- 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, µModule and Burst Mode are registered trademarks of Linear Technology Corporation.
