LTM8052/LTM8052A 36VIN, 5A, 2-Quadrant CVCC Step-Down µModule Regulator DESCRIPTION The LTM®8052/LTM8052A 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 ponents. Operating over an input voltage range of 6V to 36V, the LTM8052/LTM8052A supports an output voltage range of 1.2V to 24V. The LTM8052/LTM8052A 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. LTM8052 Features a 125% output overvoltage protection, while LTM8052A does not, allowing operation when the output is above the target regulation point. The LTM8052/LTM8052A is packaged in a pact (11.25mm × 15mm × 2.82mm) overmolded land grid array (LGA) and ball grid array (BGA) package suitable for automated assembly by standard surface mount equipment.
