RT6337規(guī)格書(shū)詳情
General Description
The RT6337 family are high efficiency synchronous
step-down DC-DC converters with pseudo constant
switching frequency 500kHz and deliver up to 9A output
current. The RT6337A/B and RT6337AH/BH operate
from 4.5V to 23V input voltage. The output voltage of
RT6337A/AH is programmed between 0.6V to 5.5V and
RT6337B/BH is fixed to 3.3V output voltage. The input
voltage of RT6337C/CH ranges from 5.2V to 23V and
the output voltage of RT6337C/CH is fixed to 5.1V.
The RT6337 adopts Advanced Constant On-Time
(ACOT?
) control architecture that provides ultra-fast
transient response and further reduces the external
component count. In steady states, the ACOT?
operates at nearly constant switching frequency over
line, load and output voltage ranges and makes the EMI
filter design easier.
By setting the voltage of the EN/MODE pin, RT6337
operates either in diode emulation mode (DEM) or
ultrasonic mode (USM) at light load. The USM
maintains operation frequency above 25kHz, which
eliminates the acoustic noise. In the DEM, RT6337
provides the best light-load efficiency and improves the
acoustic noise with spread spectrum function.
RT6337 provides PGOOD indicator for easy system
sequence control. Full protection features are also
integrated in the device, including the cycle-by-cycle
current limit, OVP, UVP, input UVLO and OTP.
All above functions are integrated in a UQFN-23L 3x3
(FC) package.
