1A STEP-DOWN VOLTAGE SWITCHING REGULATOR

Features

Description

3.3V, 5V, 12V, 15V andAdjustable output

versions

GM7110 of regulators provides all the active functions

for a step-

down (buck) switching regulator, and drives

line and load regulation.

1A load with excellent

GM7110 is available in fixed output volt ages of 3.3V,

5V, 12V, 15V and versatile Adjustable output

Adjustable version output voltage range

1.23V to 37V ±4% max over line and load

conditions

version. These regulators are simple to use and require

a minimum number of external components.

1A output current

Features include internal frequency compensation and

Requires Only 4 External Components

High Efficiency

TTL shutdown capability and low power

standby mode

Thermal shutdown, current limit protection

Uses standard inductors

a fixed- frequency oscillator. GM7110 high-efficiency

replacement for popular three-terminal linear regulators,

and is requiring a smaller heat sink or even no heat sink.

GM7110 performs well with standard inductors from

several manufacturers, and simplifying the design of

switch-mode power supplies. GM7110 guarantees ±4%

tolerance on output voltage within specified input voltages

and output load conditions, and ±10% on the oscillator

frequency.

52 kHz fixed frequency internal oscillator

External shutdown is included with 50 uA(typical)

standby current. The output switch has cycle-by-cycle

current limiting as well as thermal shutdown for full

protection under fault conditions.

Application

Pre-regulator for linear regulators

On-card/ board switching regulators

High-efficiency step-down buck regulator

Positive to negative converter (buck-boost)
