Description

The LTM®8052 is a 36VIN, 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, compact (11.25mm × 15mm × 2.82mm) RoHS compliant, overmolded land grid array (LGA) package suitable for automated assembly by standard surface mount equipment.
