MIC33M356
Overview
The Microchip MIC33M356 is a I2C programmable, high-efficiency, low-voltage input, 3A current, synchronous step-down regulator power module with integrated inductor. The Constant On-Time (COT) control architecture with HyperLight Load® mode provides very high efficiency at light loads, while still having ultra-fast transient response.
- Input Voltage Range: 2.4V to 5.5V
- 3A Output Current
- Multiple Faults Indication through I2C
- I2C Programmable: - Output voltage: 0.6V to 1.28V at 5 mV resolution or 0.6V to 3.84V, 10 and 20 mV resolution - Slew rate: 0.2 ms/V to 3.2 ms/V - On-time (switching frequency) - High-side current limit: 3.5A or 5A - Enable delay: 0.2 ms-3 ms - Output discharge when disabled (EN = GND)
- High Efficiency (up to 95%)
- Ultra-Fast Transient Response
- ±1.5% Output Voltage Accuracy Over Line/Load/Temperature Range
- Safe Start-up with Pre-Biased Output
- Typical 1.5 µA Shutdown Supply Current
- Low Dropout (100% Duty Cycle) Operation
