GENERAL DESCRIPTION
The CM2576 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 CM2576 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.
