GENERAL DEscriptION
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.
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 load to maintain high efficiency. During startup and thermal shutdown, the frequency foldbackue is used to avoid inductor current runaway for reliable and fault tolerant operation. The current limit foldbackue 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 SGM6060 is available in Green TDFN-3×3-10L and SOIC-8 (Exposed Pad) packages.
