Application
Description
Pre-regulator for linear regulators
High-efficiency step-down buck regulator
Typical Application Circuits
GM7130HV series is designed to provide all the
active function for a
regulator, and drives a maximum load current as
high as 3A
GM7130HV is
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 GM7130HV is high-efficiency replacements
for popular
requiring a smaller heat sink or even no need
heat sink.
GM7130HV performs well with standard
inductors from most
simplifying the design of
supplies.
µA (typical) standby current. The output switch
has cycle-by-cycle current limiting as well as
thermal shutdown for full protection under fault
conditions.
GM7130HV operates at a switching frequency of
52 kHz which
components than what would be needed with
lower frequency switching regulators.
GM7130HV series are available in a standard 5-
lead TO-220, TO220B and TO263 packages.
External shutdown is included with 80
line and load regulations.
