ABSOLUTE MAXIMUM RATINGS
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
Note 1: The MAX1886 is 100% production tested at T
A
= +25°C. Specifications over temperature are guaranteed by design.

Figure 1. Load Transient Test Circuit
This device is constructed using a unique set of packaging techniques that impose a limit on the thermal profile the device can be exposed to during
board level solder attach and rework. Maxim recommends the use of the solder profiles recommended in the industry-standard specification, JEDEC
020A, paragraph 7.6, Table 3 for IR/VPR and convection reflow processes. Preheating, per this standard, is required. Hand or wave soldering is not
recommended.
