GENERAL DESCRIPTION

The CM2596 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 CM2596 series offers a high-efficiency replacement for

popular three-terminal linear regulators. Also it requires a

minimum number of external components. It substantially not

only reduces the area of board size but also the size of the

heat sink, and in some cases no heat sink is required.

±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.
