GM7130HV

3A STEP DOWN VOLTAGE SWITCHING

REGULATORS

Description

Features

GM7130HV series is designed to provide all the

active function for a step-down (buck) switching

regulator, and drives a maximum load current as

high as 3A line and load regulations.

GM7130HV is available in fixed output voltages

of 3.3V, 5V, 12V and a versatile Adjustable

output version.

3.3V, 5V, 12V and Adjustable output

versions

Adjustable version output voltage range

1.23V to 57V

_OUTaccuracy is up to ±2% under

specified input voltage the output load

conditions

These regulators are simple to use and require

minimum number of external components. The

features include internal frequency compensation

and a fixed-frequency oscillator.

Input voltage range up to 60V

Requires only 4 external components with

High efficiency

The GM7130HV is high-efficiency replacements

for popular three-terminal linear regulators, and is

requiring a smaller heat sink or even no need

heat sink.

TTL shutdown capability, low power

standby mode

Built-in thermal shutdown, current limit

protection

GM7130HV performs well with standard

inductors from most of manufacturers, and

simplifying the design of switch-mode power

supplies. External shutdownis 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.

Uses standard inductors

52 kHz fixed frequency internal oscillator

Preliminary

GM7130HV operates at a switching frequency of

52 kHz which allowing smaller size filter

components than what would be needed with

lower frequency switching regulators.

GM7130HV series are available in a standard 5-

Information

lead TO-220, TO220B and TO263 packages.

Application

Pre-regulator for linear regulators

On-card/board switching regulators

High-efficiency step-down buck regulator

Positive to negative converter (buck-boost)
