SGM6022 6MHz, 600mA Synchronous Step-Down Regulator
voltage regulator, with 600mA output current
capability, that delivers a fixed output from an input
voltage supply of 2.5V to 5.5V. Using an
architecture with synchronous rectification, the
SGM6022 is capable of delivering a peak efficiency
of 90%, while maintaining efficiency over 80% at
load currents as low as 1mA.
The regulator operates at a nominal fixed frequency
of 6MHz, which reduces the value of the external
components to as low as 470nH for the output
inductor and 4.7μF for the output capacitor.
At moderate and light loads, pulse frequency
modulation (PFM) is used to operate the device in
power-save mode with a typical quiescent current of
22μA. Even with such a low quiescent current, the
part exhibits excellent transient response during
large load swings. At higher loads, the system
automatically switches to fixed-frequency control,
operating at 6MHz. Its output could be programmed
to four different voltages, as well as two different
on/off delay times, making it ideal for designing
primary supply.
The SGM6022 is available in Green TDFN-2×2-6L
package. It operates over an ambient temperature
range of -40℃ to +85℃.
