Using the RCBL Pin as Output Current Monitor Selection of the operating frequency is a trade-off between efficiency, component size and input voltage range. The advantage of high frequency operation is that smaller inductor and capacitor values may be used. The disadvan- tages are lower ...

Since both conduc- tion paths have low losses, this approach can result in very high efficiency (90% to 95%) in most applications. For regulators under 10A, using low RDS(ON) N-channel MOSFETs eliminates the need for heat sinks. RGS holds the top MOSFET off when HV is applied before ...
