DescripTion
The LTM
®
8052 is a 36V
IN
, 5A, 2-quadrant constant-voltage,
constant-current (CVCC) step-down μModule
®
regulator.
Included in the package are the switching controller, power
switches, inductor and support components. Operating
over an input voltage range of 6V to 36V, the LTM8052
supports an output voltage range of 1.2V to 24V. The
LTM8052 is able to sink or source current to maintain
voltage regulation up to the positive and negative current
limits. This output current limit can be set by a control
voltage, a single resistor or a thermistor.
The LTM8052 is packaged in a thermally-enhanced, com-
pact (11.25mm × 15mm × 2.82mm) RoHS compliant,
overmolded land grid array (LGA) package suitable for au-
tomated assembly by standard surface mount equipment.
