- Wide Input Voltage Range: 4~23V
- Integrated Bypass Switch: 1.5Ω
- Instant PWM Architecture to Achieve Fast Transient Responses
- Internal 1.2ms Soft-start Limits the Inrush Current
- Pseudo-constant Frequency: 600kHz
- Fixed 3.338V Output Voltage
- 4A Output Current Capability
- 100mA LDO Current Capability
- ±1% Internal Reference Voltage
