SGM61411

150kHz, 600mA, 42V

Synchronous Buck Converter

GENERAL DESCRIPTION

FEATURES

The SGM61411 is a synchronous Buck converter with

integrated switches. It can deliver up to 600mA to the

output over a wide input voltage range of 5V to 42V. It

is suitable for various industrial or automotive

applications with high input voltage or for power

conditioning from unregulated sources. Moreover,

ultra-low shutdown current of only 0.6µA make it a

suitable choice for battery-powered applications.

● Wide 5V to 42V Operating Input Voltage Range

● 0.8V Internal Reference

● Shutdown Current: 0.6μA (TYP)

● Current Output up to 600mA

● 150kHz Switching Frequency

● Internal Compensation and Soft-Start

● Simple Design and Minimal External Components

● Up to 95% Efficiency at 12V/400mA

● 0.8V to 20V Adjustable Output Voltage

● Current Limit and Short-Circuit Protection

● Output Over-Voltage Protection and Thermal

Shutdown

SGM61411 features high efficiency over a wide load

range. Other features include internal compensation,

internal monotonic soft-start even with pre-biased

output. Switching at 150kHz, the SGM61411 can

prevent EMI noise problems, such as the ones found in

AM radio, ADSL and PLC applications.

● Forced PWM Control Mode Operation

● Monotonic Startup with Pre-biased Output

● 98% Maximum Duty Cycle

● Available in a Green SOT-23-6 Package

● -40℃ to +125℃ Operating Temperature Range

Protection features include current limiting and

short-circuit protection, thermal shutdown with auto

recovery and output over-voltage protection.

SGM61411 is available in a Green SOT-23-6 package.
