Application
Description
Pre-regulator for linear regulators
High-efficiency step-down buck regulator
Typical Application Circuits
GM7130 series is designed to provide all the
active function for a
regulator, and drives a maximum load current as
high as 3A
available in fixed output voltages of 3.3V, 5V,
12V and a versatile Adjustable output version.
These regulators are simple to use and require
minimum number of external components. The
features include internal frequency compensation
and a fixed-frequency oscillator.
The GM7130 is high-efficiency replacements for
popular
requiring a smaller heat sink or even no need
heat sink.
GM7130 performs well with standard inductors
from most
design of
shutdown is included with 80 µA (typical) standby
current. The output switch has cycle-by-cycle
current limiting as well as thermal shutdown for
full protection under fault conditions.
GM7130 operates at a switching frequency of
52 kHz which
components than what would be needed with
lower frequency switching regulators.
GM7130 series are available in a standard 5-lead
TO-220, TO220B and TO263 packages.
