The SA24492 is a high-efficiency synchronous step-down DC-DC converter capable of delivering a load current of 2A. 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 SA24492 uses a peak current control architecture. The switching frequency is adjustable from 300kHz to 2.2MHz using an external resistor. The SA24492 features ultra-low quiescent current to achieve high efficiency under light load conditions. Additionally, the internal soft-start function limits inrush current during power-up.
The SA24492 is available in a QFN2×2-12 Package.
