NCP3233
High Current Synchronous
Buck Converter
The NCP3233 is a high current, high efficiency voltage−mode
synchronous buck controller which operates from 3.0 V to 21 V input
and generates output voltages down to 0.6 V at up to 20 A.
Features
• Wide Input Voltage Range from 3.0 V to 21 V
• 0.6 V 1% Accurate Internal Reference Over Temperature
• Fixed Switching Frequency: 500 kHz (1 MHz and 300 kHz options
contact factory)
• External Programmable Soft−Start
• Lossless Low−side and High−side FET Current Sensing
• Output Overvoltage Protection and Undervoltage Protection
• Recoverable Overvoltage Protection
• Hiccup Mode Operation for UVP, LS OCP and TSD
• Pre−bias Start−up
• Adjustable Output Voltage
• Power Good Output
• Internal Overtemperature Protection
• Adjustable Input UVLO
• This is a Pb−Free Device
Typical Application
• Cellular Base Stations
• ASIC, FPGA, DSP and CPU Core and I/O Supplies
• Telecom and Network Equipment
• Server and Storage System
