General Description
TS2596S Series are step-down switching regulators with all required active functions. It is capable of driving 2A load
with excellent line and load regulations. These devices are available in fixed output voltages of 3.3V, 5V, and an
adjustable output version.
TS2596S 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 70µA (typical) standby current. The output switch includes cycle-by-
cycle current limiting, as well as thermal shutdown for full protection under fault conditions.
