Semtech SC4524D
18V 2A Step-Down Switching Regulator
Not Recommended for New Designs, Recommended Replacement Part is SC4524F
The SC4524D is a constant frequency peak current-mode step-down switching regulator capable of producing 2A output current from an input ranging from 3V to 18V. The switching frequency of the SC4524D is programmable up to 2MHz, allowing the use of small inductors and ceramic capacitors for miniaturization, and high input/output conversion ratio.
To convert your designs from SC4524B, please refer to our
"SC4524A/B to SC4524C/D Design Guide" in the documents section below
