3A STEP-DOWN VOLTAGE SWITCHING REGULATORS
Description
Gl2576 of regulators provides all the active functions for
a step-down (buck) switching regulator, and drives 3A
load with excellent line and load regulation. GL2576 is
available in fixed output voltages of 3.3V, 5V, 12V,
15V, and a versatile Adjustable output version. These
regulators are simple to use and require a minimum
number of external components. Features include inter-
nal frequency compensation and a fixes-frequency oscil-
lator. The GL2576 is high-efficiency replacements for
popular three-terminal linear regulators, and is requiring
a smaller heat-sink or even no heat-sink. GL2576 per-
forms well with standard inductors from several manu-
facturers, and simplifying the design of switch-mode
power supplies. GL2576 guarantees ± 4% tolerance on
output voltage within specified input voltages and output
load conditions, and ± 10% on the oscillator frequency.
External shutdown is included with 50μ A (typical)
standby current. The output switch has cycle-by-cycle
current limiting as well as thermal shutdown for full pro-
tection under fault conditions.
