SGM6330

3A, 18V, 385kHz Buck Converter

GENERAL DESCRIPTION

FEATURES

The SGM6330 is a current-mode Buck regulator with

an internal power MOSFET. It can operate at an input

voltage from 4.5V to 18V with 0.8V to 15V adjustable

output. A fixed 385kHz switching frequency helps the

device to provide fast transient response. It also offers

a 3A continuous output current and a peak efficiency of

94% with excellent load and line regulations.

● 4.5V to 18V Input Voltage Range

● 0.8V to 15V Adjustable Output

● 3A Output Current

● Up to 94% High Efficiency

● Fixed 385kHz Switching Frequency

● Less than 18µA Shutdown Supply Current

● 100mΩ Internal Power MOSFET Switch

● Under-Voltage Lockout (UVLO)

● Thermal Shutdown Protection

In off mode, the voltage regulator's supply current is

less than 18µA. This device also equips the

under-voltage lockout (UVLO), cycle-by-cycle current

limit and thermal shutdown features. The internal

soft-start function and the external adjustable soft-start

function help the device to limit the inrush current and

prevent output voltage overshooting.

● Stable with Low ESR Ceramic Capacitors

● -40℃ to +85℃ Operating Temperature Range

● Available in a Green SOIC-8 (Exposed Pad) Package

APPLICATIONS

The SGM6330 is available in a Green SOIC-8

(Exposed Pad) package. It operates over an ambient

temperature range of -40℃ to +85℃.
