FEATURES DESCRIPTION
n
Complete Step-Down Switch Mode Power Supply
The LTM®8025 is a 36VIN, 3A step-down µModule® n
Wide Input Voltage Range: 3.6V to 36V
(micromodule) converter. Included in the package are n
Up to 3A Output Current
the switching controller, power switches, inductor and n
Parallelable for Increased Output Current
all support components. Operating over an input voltage n
0.8V to 24V Output Voltage
range of 3.6V to 36V, the LTM8025 supports an output n
Selectable Switching Frequency: 200kHz to 2.4MHz
voltage range of 0.8V to 24V and a switching frequency n Current Mode Control range of 200kHz to 2.4MHz, each set by a single resistor. n SnPb or RoHS Compliant Finish Only the bulk input and output filter capacitors are needed n Programmable Soft-Start to finish the design. n 9mm × 15mm × 4.32mm LGA and 9mm × 15mm × The LTM8025 is packaged in a thermally enhanced, com- 4.92mm BGA Packages pact (9mm × 15mm) and low profile over-molded land
APPLICATIONS
grid array (LGA) and ball grid array (BGA) packages suit- able for automated assembly by standard surface mount n equipment. The LTM8025 is available with SnPb (BGA) Automotive Battery Regulation n or RoHS compliant terminal finish.
