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.

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.

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℃.
