SC2620SETRT

The SC2620SETRT belongs to the SC2620 series.It is a kind of constant frequency dual current-mode switching regulator.It uses small inductors and ceramic capacitors because of its high frequency operation.It can achieve fast transient response with simple loop compensation and can be used in XDSL and cable modems,set-top boxes,point of load applications and CPE equipment DSP power supplies.

The following is about its features.(1) wide input voltage range: 2.8 V to 30 V;(2) up to 1.4MHz/channel programmable switching frequency; (3) current-mode control; (4) out of phase switching reduces ripple; (5) cycle-by-cycle current-limiting; (6) independent shutdown/soft-start pins; (7) independent hiccup overload protection; (8) channel 1 power good indicator; (9) two 2.3 A integrated switches; (10) thermal shutdown; (11) thermally enhanced SO-16 lead free package; (12) flly WEEE and RoHS compliant.

What comes next is about absolute maximum ratings.(1): the maximum input voltage is from -0.3 V to 32 V; (2): the maximum boost pin is 42 V; (3): boost pin above SW is 24 V; (4): SS pins is 3 V; (5): SW voltage is -0.6 V to VIN; (6): operating ambient temperature range is from -40 to 85; (7): thermal resistance junction to ambient is 31 /W; (8): thermal resistance junction to case is 3.9 /W; (9): storage temperature ranges from -65 to 150; (10): ESD rating is 1500 V; (11): the minimum input voltage is 2.8 V and the maximum is 30 V; (12): the typical quiescent current is 3.5 A and the maximum is 5 A at no switching and PGOOD1 is open.
