The RTQ6345 is a 5A, high-efficiency, peak current mode
control asynchronous step-down converter. The device
operates with input voltages from 4V to 42V. The device
can program the output voltage between 0.8V to VIN. The
low quiescent current design with the integrated low RDS(ON)
of high-side MOSFET achieves high efficiency over the
wide load range. The peak current mode control with simple
external compensation allows the use of small inductors
and results in fast transient response and good loop
stability.
The wide switching frequency of 100kHz to 2500kHz allows
for efficiency and size optimization when selecting the
output filter components. The ultra-low minimum on-time
enables constant-frequency operation even at very high
step-down ratios. For switching noise sensitive
applications, it can be externally synchronized from
300kHz to 2200kHz. RTQ6345GSP RTQ6345GQW资料下载
