Product Overview
- High frequency step-down switching regulator in 10 pin TQFN-EP package
- 120μA quiescent current
- 300mohm internal power MOSFET
- Stable ceramic capacitor
- Internal soft-start
- Precision current limit without a current sensing resistor
- Up to 95% efficiency
- Frequency foldback helps prevent inductor current runaway during start-up and thermal shutdown
