0.8V to 10V Output Voltage
1A Output Current
Adjustable Switching Frequency: 200kHz to 2.4MHz
Current Mode Control
(e4) RoHS Compliant Package with Gold Pad Finish
Programmable Soft-Start
Tiny, Low Profile (11.25mm × 9mm × 2.82mm) Surface Mount LGA Package

The LTM8022 is a complete 1A, DC/DC μModule (power module) step-down regulator. Included in the package are the switching controller, power switches, inductor, and all support components. Operating over an input voltage range of 3.6V to 36V, the LTM8022 supports an output voltage range of 0.8V to 10V, and a switching frequency range of 200kHz to 2.4MHz, each set by a single resistor. Only the bulk input and output filter capacitors are needed to finish the design.

The low profile package (2.82mm) enables utilization of unused space on the bottom of PC boards for high density point of load regulation.

The LTM8022 is packaged in a thermally enhanced, compact (11.25mm × 9mm) and low profile (2.82mm) overmolded land grid array (LGA) package suitable for automated assembly by standard surface mount equipment. The LTM8022 is RoHS compliant.

Product Details

Demonstration circuit 1261A features the LTM8022 step-down μModule^® regulator delivering a 3.3V/1A output from a 4.5V to 36V input supply. As a step-down converter, the LTM8022 requires a minimum amount of headroom to keep the output in regulation. Current sharing with another LTM8022 is enabled by tying the V_IN, V_OUT and SHARE pins together to support higher output loads.
