SGM61310

4V to 36V Input, 1A Synchronous

Buck Converter in SOT Package

GENERAL DESCRIPTION

FEATURES

The SGM61310 is a synchronous Buck converter with a

wide input voltage range of 4V to 36V. This device can

deliver up to 1A to the output over a wide input voltage.

It is an easy-to-use device with power switches and

peak current mode control compensation all integrated

in a small 6-pin package. A typical 1.8ms soft-start

ramp is also included to minimize the inrush current.

This device can be easily used in various industrial

applications powered from unregulated sources.

● Documentation Available to Aid Functional

Safety System Design

● Wide 4V to 36V Input Voltage Range

● Up to 1A Continuous Output Current

● Minimum Switching On-Time: 60ns

● 700kHz Fixed Switching Frequency

● 98% Maximum Duty Cycle

● Monotonic Startup with Pre-Biased Output

● Internal Short-Circuit Protection with Hiccup

Mode

This device employs cycle-by-cycle peak current limit,

output over-voltage protection and thermal shutdown

with auto recovery. The current limit is implemented for

switches to prevent overheating (and thermal shutdown)

when an output short is detected. Auto recovery after

over-current, output short, overheating or over-voltage

fault maintains the system operational with no

shutdown.

● Precision Enable

● Integrated Synchronous Rectification

● Internal Compensation for Ease of Use

● Pin-to-Pin Compatible with SGM61410 and

SGM61306

● SGM61310A: PSM at Light Load Condition

● SGM61310B: FPWM at Light Load Condition

● -40℃ to +125℃ Operating Temperature Range

● Available in a Green SOT-23-6 Package

The SGM61310 operates at 700kHz switching frequency

to support use of relatively small inductors for an

optimized solution size. In light load condition, the

SGM61310A enters in the pulse skip modulation (PSM)

mode to improve high efficiency, while the SGM61310B

works in the forced pulse width modulation (FPWM)

mode to achieve low output ripple.

APPLICATIONS

Grid Infrastructure: Advanced Metering Infrastructure

Motor Drive: AC Inverters, VF Drives, Servos, Field

Actuators

Factory and Building Automation: PLC, Industrial PC,

Elevator Control, HVAC Control

The SGM61310 is available in a Green SOT-23-6

package.
