SY8113E1 Overview
Description
The SY8113E1 is a high efficiency, 500 kHz synchronous step-down DC/DC regulator capable of delivering up to 3A load current. It can operate over a wide input voltage range from 4.5V to 18V and integrate 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): 80mΩ/40mΩ
- 4.5-18V Input Voltage Range
- 3A Output Current Capability
- 500 kHz Switching Frequency Minimize the External Components
- Stable with 10µF COUT and 2.2µH Inductor
- Instant PWM Architecture to Achieve Fast Transient Responses
- Internal Soft-start Limits the Inrush Current
- Forced PWM Operation
- Cycle-by-cycle Peak/Valley Current Limitation
- Hic-cup Mode Output Short Circuit Protection
