LTC3828
Overview
The LTC®3828 is a dual high performance step-down switching regulator controller that drives all N-channel synchronous power MOSFET stages. A constant frequency current mode architecture allows for a phase-lockable frequency of up to 550kHz.
- Dual, 180° Phased Controllers Reduce Required Input Capacitance and Power Supply Induced Noise
- Tracking for Both Outputs
- Constant Frequency Current Mode Control
- Wide VIN Range: 4.5V to 28V Operation
- Power Good Output Voltage Indicator
- Adjustable Soft-Start Current Ramping
- Foldback Output Current Limiting- Disabled at Start-Up
- No Reverse Current During Soft-Start Interval
- Clock Output for 3-, 4-, 6-Phase Operation
- Dual N-Channel MOSFET Synchronous Drive n ±1% Output Voltage Accuracy
