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 80µA (typical) standby current. The output switch includes
cycle-by-cycle current limiting, as well as thermal shutdown for full protection under fault conditions.
