SGM61164

4.5V to 18V Input, 6A,

Synchronous Buck Converter

GENERAL DESCRIPTION

FEATURES

The SGM61164 is an efficient, 6A, synchronous, Buck

converter with integrated power MOSFETs and a wide

4.5V to 18V input range. This current mode control

device is optimized for high density applications with

minimal number of external components. High

switching frequency, up to 2MHz, can be chosen to

lessen the solution size by smaller inductor and

capacitors. This device can be used as a standalone or

tracking power supply. The SS/TR pin can be used to

control the output voltage startup ramp or as an input

for tracking.

● Low Integrated R_DSONSwitches: 27mΩ/18mΩ

● Split Rails for Supply (VIN) and Power (PVIN)

 1.8V to 18V Range for PVIN

 4.5V to 18V Range for VIN

● 200kHz to 2MHz Switching Frequency

● External Clock Synchronization

● Voltage Tracking Capability

● 0.8V Internal Reference Voltage

● ±1% Reference Voltage Accuracy

● 3.4μA (TYP) Shutdown Current

● Monotonic Startup with Pre-biased Outputs

● Adjustable Soft-Start Time

● Power Sequencing Capability

● Power Good Output Monitor for Under-Voltage

and Over-Voltage Protections

Power supply sequencing for two or more power

supplies is possible by using the enable input (EN) and

the open-drain power good output (PG) signals.

The high-side MOSFET current is cycle-by-cycle

limited for overload protection. The low-side MOSFET

sourcing current is also limited to prevent current

runaway. The low-side switch also has a sinking

current limit that turns it off if an excessive reverse

current flows through it.

● Adjustable Input Under-Voltage Lockout (UVLO)

● Available in a Green TQFN-3.5×3.5-14L Package

APPLICATIONS

Industrial and Commercial Power Systems

Distributed Power Systems

Server and Storage

Thermal shutdown protection is activated to prevent

damage to the device when the junction temperature is

above the shutdown threshold.

Communications Equipment

The SGM61164 is available in a Green TQFN-3.5×3.5-14L

package.
