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.

APPLICATIONS

ꢀ

LCD Monitors

ADD-ON Cards Switching Regulators

High Efficiency Step-Down Regulators

Car Electronic
