SQ20953 Overview
Description
The SQ20953 develops a high efficiency synchronous step-down DC/DC converter ， which is capable of delivering 3A load current. The SQ20953 operates over a wide input voltage range from 4.5V to 30V and integrates main switch and synchronous switch with very low RDS(ON) to minimize the conduction loss.
Key Features
- Low RDS(ON) for Internal Switches (Top/Bottom): 110/70 mΩ
- 4.5-30V Input Voltage Range
- Internal Compensation
- Internal 1ms Soft-start Limits the Inrush Current
- Adjustable Switching Frequency Range: 500kHz to 2.5MHz
