The current limit block is required to manage the inrush current on power up. Consider a battery pack with an impedance of 120m Ω and a supercap with an ESR = 80mΩ. If the battery is at 3.7V then the inrush current = 3.7V/200mΩ = 18.5A. A suitable current limit

1-A (Typical) Operating Current Limit It also features a 100-V pass transistor, 140-mA • 15 kV and 8 kV System-level ESD Capability inrush current limiting, type-2 indication, auto-retry • PowerPAD™ HSOP Package fault protection, and an open-drain power-good output. 2 Applications Device Information(1)

Thehotswap MOSFET will be re-enabled with the inrush current limit when exiting from an over-temperature event.Pulling DEN to VSS during powered operation causes the internal hotswap MOSFET to turn off. This featureallows a PD with option three ORing per Figure 23 to achieve adapter priority.The hotswap switch will be forced off under the ...

LEDs are best driven with a constant current source, but unlike most system loads, they do not have to be ground referenced. Therefore, the LT3477 with its floating current sense amplifiers can be converted into a buck LED driver with low LED ripple current. Figure 295.2 shows a 32V input voltage buck converter driving a string of 1A LEDs.
