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.
