- Wide Input Voltage Range: 4~24V
- Integrated Bypass Switch: 1.5Ω
- Instant PWM Architecture to Achieve Fast Transient Responses
- Internal Soft-start Limits the Inrush Current
- Pseudo-constant Frequency: 600kHz
- Fixed 3.36V Output Voltage
- 10A Output Current Capability
- 100mA LDO Current Capability
- ±1% Internal Reference Voltage
