BM2576
3A DC/DC
GENERAL DESCRIPTION
FEATURES
The BM2576 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 ꢀ
Guaranteed 3A output current
3.3V, 5V, and adjustable versions
Wide input voltage range, up to 40V
available in fixed output voltages of 3.3V, 5V, and an
adjustable output version.
ꢀ
ꢀ
Internal oscillator of 52KHz fixed frequency
Wide adjustable version output voltage range, from
1.23V to 37V±4% max over line and load conditions
Low standby current, typ. 70µA, at shutdown mode
Requires only 4 external components
The BM2576 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.
Thermal shutdown and current limit protection
P+ product enhancement tested
±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.
