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℃.
