NCP5383: Two Phase Buck Controller with Integrated Gate Drivers and AVP
For complete documentation, see the data sheet
Product Description
The NCP5383 is a two phase buck controller used in low voltage, high current power supplies. Dual edge pulse width modulation
combined with inductor current sensing and adaptive voltage positioning reduces system cost by providing the fastest initial
response to transient loads thereby requiring less bulk and ceramic output capacitors to satisfy transient load line requirements. A
high performance operational error amplifier is provided, which allows for easy compensation of the system. Protection features
include overcurrent protection, undervoltage lockout and thermal shutdown and power good monitor.
