The SC4530 is a 30 V micropower buck regulator that provides light-load efficiency greater than 80% at 650 µA output and an ultra-small, 50 mm2 solution footprint. The combination of features addresses the key requirements for long battery life, small size and design simplicity in notebook PCs and set-top box applications.
The SC4530 operates from a 3 V to 30 V supply and provides an adjustable output voltage with output current up to 300 mA. The very-wide input voltage range enables the device to operate from a variety of input sources, including single- or multi-cell batteries, internal system rails, and wall adapters.
Availability and Pricing
The SC4530 is available immediately in production quantities and is priced at $0.58 each in 3,000-piece lots. The ordering code is SC4530WLTRT. Evaluation boards (SC4530EVB) are also available. Semtech offers comprehensive design assistance, including field- and factory-based support.
