SGM6061

55V, 1.5A High Frequency Buck Converter

GENERAL DESCRIPTION

FEATURES

The SGM6061 is a high voltage and high frequency

Buck converter with 1.5A maximum output current and

integrated high-side power MOSFET. It implements

peak current mode control to simplify external

compensation design.

● Input Voltage Range: 3.8V to 55V

● Adjustable Output Range: 0.8V to 24V

● Up to 95% Efficiency

● PFM Mode at Light Loads

● Quiescent Current: 131μA (TYP)

● Less than 18μA Shutdown Current

● Internal HS Power MOSFET R_DSON: 250mΩ (TYP)

● Adjustable Switching Frequency: up to 2MHz

● Adjustable Soft-Start Time

With a wide input voltage range of 3.8V to 55V, it is

suitable for a broad range of applications such as

industry equipment.

The SGM6061 operates at fixed frequency and enters

PFM (Pulse Frequency Modulation) mode automatically

at light load to maintain high efficiency. During startup

and thermal shutdown, the frequency foldback

technique is used to avoid inductor current runaway for

reliable and fault tolerant operation. The current limit

foldback technique is used for reducing power

consumption during output shorted and suppressing

output voltage overshot during recovery.

● Accurate EN Input Threshold

● Stable with Ceramic Capacitor

● Available in a Green TDFN-3×3-10L Package

APPLICATIONS

Industrial and Commercial Power Systems

Distributed Power Systems

Aftermarket Automotive Accessories

Switching frequency can be set as high as 2MHz. It

minimizes the EMI noise issues that could interfere with

nearby systems such as AM radio or ADSL modems.

The SGM6061 is available in a Green TDFN-3×3-10L

package. It operates over a junction temperature range

of -40℃ to +125℃.
