Power chip test: TSDSO package chip type, characteristics, and corresponding chip test seat detailed explanation
TSDSO of power chip package type:
As an important part of electronic devices, the testing of power chips is crucial. Among them, TSDSO package type has become an important evaluation index in power chip testing.
Power chip
TSDSO package type, namely "D2-PAK" or "TO-263", according to the engineer of Hongyi electronic chip test seat: TSDSO package adopts the optimized design of foot pitch, arrangement density, etc., so that it has high power carrying capacity and electrical performance. In power chip testing, power chips using TSDSO packages can effectively reduce the on-voltage drop, improve efficiency, and reduce losses.
In addition to the above features, the TSDSO package type power chip has some other advantages. For example, the power chip of the TSDSO package type has lower power consumption and can better meet the requirements of energy saving and environmental protection. In addition, the TSDSO package type power chip has a higher operating frequency to better meet the needs of high-performance equipment
In the process of power chip testing, in addition to the type of package, its characteristics are also a very important assessment index. Power chips usually have the characteristics of constant voltage output, constant current output, output voltage, output current, etc. Among them, constant voltage output means that the output voltage is always maintained as a constant value when the output current is unchanged; Constant current output means that the output current is always kept at a constant value when the output voltage is unchanged. Power chip testing needs to pay attention to these characteristics, and choose the appropriate test means according to actual needs.
In addition, it is also necessary to pay attention to the test of electrical performance in the power chip test. Electrical performance includes input voltage range, input current range, output voltage range, output current range, efficiency and other indicators. During the test, it is necessary to select and arrange the test links according to the actual situation of the power chip to ensure the accuracy and reliability of the test results.

The difference between the TSDSO package type of the power chip and the conventional BGA77/144 chip:
Relatively speaking, conventional BGA144/77 package type power chips have their own unique advantages in some aspects. For example, the BGA144/77 package type power chip is relatively low in cost and more suitable for some price-sensitive application scenarios. In addition, the BGA144/77 package type of power chips has higher yields and is better able to meet the needs of mass production.
The TSDSO package type is an emerging packaging technology that has some very unique features. First, the TSDSO package type is smaller than the traditional BGA144/77 package type. This means that TSDSO-packaged power chips can achieve a higher level of integration in a smaller space, bringing greater flexibility and scalability to the design of electronic devices.

Secondly, the TSDSO package type also has certain advantages in terms of thermal design. The TSDSO package adopts a unique thermal heat dissipation structure, which can better disperse heat and reduce the temperature of the chip. In contrast, the BGA144/77 package type has slightly inferior thermal performance. In high-temperature environments, power chips in TSDSO packages can better maintain stability and reliability.
In addition, the TSDSO package type has higher protection capabilities. Due to its small size and unique package structure, the TSDSO package type power chip can better resist external interference and vibration. In contrast, the BGA144/77 package type power chip is relatively fragile and susceptible to interference from the external environment.
Compared with conventional BGA144/77 package type power chips, TSDSO package type power chips have many advantages and characteristics. TSDSO package type power chips perform well in terms of size, thermal design, and protection capabilities. However, power chips in the BGA144/77 package type offer advantages in terms of cost and yield. Therefore, the choice of which package type of power chip should be weighed and selected according to the specific application scenario and requirements.
