Abstract

The invention relates to a power supply module test device, comprising a test base. The test base is provided with a test circuit and a contact member which is used for matching with contacts of the power supply module in a press-contact mode. The contact member is electrically connected to the test circuit. During usage, the power supply module is connected to the test circuit through the pressing match between the contact member of the test base and the contacts of the power supply module, the contacts are guaranteed not to be damaged, and at the same time, a quick test of the power supply module is realized.

Description

technical field [0001] The invention relates to a power module testing device. Background technique [0002] The LTM4600 power module is a contact array packaged power supply DC / DC conversion chip, the input voltage range is 4.5V-20V, the output voltage range can be from 0.6V-5V (determined by a single peripheral resistor), and the maximum output current can reach 10A , the peak current can reach 14A, the output voltage adjustment rate can reach 1.5%, the highest efficiency can reach 92%, the transient response speed is super fast, the typical switching frequency is 850KHz, there is a signal output of good power supply, and there is output overvoltage Protection and optional short-circuit shutdown timer. However, this power module has no pins and no solder balls, and its bottom is a square plate electrode in an array state. The contact density of the electrodes is high. Or solder balls are welded in the test circuit for detection), the second screening cannot be carried ou...
