The SA24483 is a high efficiency synchronous step-down DC-DC converter capable of delivering a load current of 3A. It operates over a wide input voltage range of 4.5V to 36V and integrates main and synchronous MOSFET switches with very low RDS(ON) to minimize conduction loss.
The SA24483 uses a peak current control scheme. The switching frequency is adjustable from 300kHz to 2.2MHz using an external resistor. The SA24483 features frequency reduction and ultralow quiescent operating to achieve high efficiency under light load. Additionally, the internal soft-start function limits inrush current during power-up.
The SA24483 is available in a QFN2×2-12 Package.
