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.

A high performance operational error amplifier is provided, which

allows for easy compensation of the system. Protection features

include overcurrent protection, undervoltage lockout (UVLO),

thermal shutdown and power good monitor.
