Exposure to absolute maximum rated conditions for extended periods may affect device reliability. 2/ All voltages are within respect to network ground terminal. 3/ Approaching the absolute maximum rating for the VINpin may cause the voltage on the PH pin to exceed the absolute ma

The manufacturer and/or distributor maintain no responsibility or liability for product used beyond the stated limits. 5/ Maximum power dissipation may be limited by overcurrent
13、 protection. 6/ Power rating at a specific ambient temperature TAshould be determined with a junction temperature of 125C. This is the point where distortion starts to substantially increase. Thermal management of the final printed circuit board (PCB) should strive to keep the junction temperature a

See thermal calculations in the application section of the manufacturers datasheet for more information. 7/ Test board conditions: 2 inch x 1.85 inch, four layers, 0.062 inch (1.57 mm) thickness. 2 ounce copper traces located on the top and
15、bottom of the PCB. 2 ounce copper ground planes on the two internal layers. Four thermal vias in the thermal pad area under the device package.
