NCP5383
2 Phase Buck Controller
with Integrated Gate
Drivers and AVP
The NCP5383 is a two phase buck controller used in low voltage,
high current power supplies. Dual-edge pulse-width modulation
(PWM) combined with inductor current sensing and adaptive voltage
positioning (AVP) 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.
