RT6363
Description
The RT6363 is a 3.5A, high-efficiency, peak current mode control asynchronous step-down converter. The device operates with input voltages from 4V to 60V. 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 pensation allows the use of small inductors and results in fast transient response and good loop stability.
The wide switching frequency of 100k Hz to 2500k Hz allows for efficiency and size optimization when selecting the output filter ponents. 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 300k Hz to 2200k Hz.
The RT6363 provides plete protection functions such as input under-voltage lockout, output under-voltage protection, output...
