SC1480EVB

Manufacturer Part Number
SC1480EVB
Description
DDR Memory Power Supply Controller
Manufacturer
SEMTECH [Semtech Corporation]
Datasheet
Test Conditions: V
Notes:
(1) When the inductor is in continuous conduction mode, the output voltage will have a DC regulation level higher
than the error-comparator threshold by 50% of the ripple voltage.
(2) Using a current sense resistor, this measurement relates to PGND minus the voltage of the source on the
low-side MOSFET.
(3) This device is ESD sensitive. Use of ESD handling precautions is required.
(4) Measured in accordance with JESD51-1, JESD51-2 and JESD51-7.
