LTM8022 1A, 36V DC/DC µModule
FEATURES DESCRIPTION
n
Complete Step-Down Switch Mode Power Supply
The LTM®8022 is a complete 1A, DC/DC step-down power n
Wide Input Voltage Range: 3.6V to 36V
supply. Included in the package are the switching controller, n
0.8V to 10V Output Voltage
power switches, inductor, and all support components. n
1A Output Current
Operating over an input voltage range of 3.6V to 36V, the n
Adjustable Switching Frequency: 200kHz to 2.4MHz
LTM8022 supports an output voltage range of 0.8V to 10V, n Current Mode Control and a switching frequency range of 200kHz to 2.4MHz, n (e4) RoHS Compliant Package with Gold Pad Finish each set by a single resistor. Only the bulk input and output n Programmable Soft-Start fi lter capacitors are needed to fi nish the design. n Tiny, Low Profi le (11.25mm × 9mm × 2.82mm) The low profi le package (2.82mm) enables utilization of Surface Mount LGA Package unused space on the bottom of PC boards for high density point of load regulation.
APPLICATIONS
The LTM8022 is packaged in a thermally enhanced, compact n (11.25mm × 9mm) and low profi le (2.82mm) overmolded Automotive Battery Regulation n land grid array (LGA) package suitable for automated Power for Portable Products n assembly by standard surface mount equipment. The Distributed Supply Regulation n LTM8022 is RoHS compliant. Industrial Supplies n Wall Transformer Regulation L, LT, LTC, LTM, Linear Technology, Burst Mode and the Linear logo are registered trademarks of Linear Technology Corporation. All other trademarks are the property of their respective owners.
