General Description
The TS2596 Series are step-down switching regulators with all required active functions. It is capable of driving
3A load with excellent line and load regulations. These devices are available in fixed output voltages of 3.3V, 5V,
and an adjustable output version.
The TS2596 series operates at a switching frequency of 150kHz thus allowing smaller sized filter components
than what would be needed with lower frequency switching regulators. It substantially not only reduces the area of
board size but also the size of heat sink, and in some cases no heat sink is required. The ±4% tolerance on output
voltage within specified input voltages and output load conditions is guaranteed. Also, the oscillator frequency
accuracy is within ±10%. External shutdown is included. Featuring 100µA (typical) standby current. The output
switch includes cycle-by-cycle current limiting, as well as thermal shutdown for full protection under fault
conditions.

Pin Function Description (Continue)
Thermal Considerations

but with copper areas greater than approximately 6 in , only small improvements in heat dissipation are realized. If
further thermal improvements are needed, double sided, multilayer PC board with large copper areas and/or airflow
are recommended.
The TS2596 (TO-263-5L package) junction temperature rise above ambient temperature with a 3A load for various
input and output voltages. This data was taken with the circuit operating as a buck switching regulator with all
components mounted on a PC board to simulate the junction temperature under actual operating conditions. This
curve can be used for a quick check for the approximate junction temperature for various conditions, but be aware
that there are many factors that can affect the junction temperature. When load currents higher than 3A are used,
double sided or multilayer PC boards with large copper areas and/or airflow might be needed, especially for high
ambient temperatures and high output voltages.
For the best thermal performance, wide copper traces and generous amounts of printed circuit board copper
should be used in the board layout. (Once exception to this is the output (switch) pin, which should not have large
areas of copper.) Large areas of copper provide the best transfer of heat (lower thermal resistance) to the
surrounding air, and moving air lowers the thermal resistance even further.
