NCP5383 Datasheet (ON Semiconductor) - 2 Phase Buck Controller

NCP5383, 2 Phase Buck Controller

Pin No.

1 Symbol ROSC Description A resistance from this pin to ground programs the oscillator frequency according to fSW = 1 / (ROSC w 100ĂpF).

Also, this pin supplies a trimmed output voltage of 2.00 V so it may be used to form a voltage divider at the ILIM pin to set the over current shutdown th

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
