SGM6060

55V, 2A High Frequency Buck Converter

GENERAL DESCRIPTION

FEATURES

The SGM6060 is a high voltage and high frequency

Buck converter with 2A maximum output current and

integrated high-side power MOSFET. It implements

peak current mode control to simplify external

compensation design.

● 3.8V to 55V Wide Input Voltage Range

● Adjustable Output Voltage

● Up to 95% Efficiency

● PFM Mode at Light Loads

● Quiescent Current: 126μA (TYP)

● Less than 18μA Shutdown Current

● Internal HS Power MOSFET R_DSON: 220mΩ (TYP)

● Adjustable Switching Frequency: 200kHz to 2MHz

● Internal Soft-Start Circuit

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 SGM6060 operates at fixed frequency and enters

PFM (Pulse Frequency Modulation) mode automatically

at light loads 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 Green TDFN-3×3-10L and SOIC-8

(Exposed Pad) Packages

APPLICATIONS

Industrial and Commercial Power Systems

Distributed Power Systems

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.

Aftermarket Automotive Accessories

The SGM6060 is available in Green TDFN-3×3-10L

and SOIC-8 (Exposed Pad) packages.
