NX9415

5A SYNCHRONOUS BUCK SWITCHING REGULATOR

PRODUCTION DATA SHEET

Pb Free Product

FEATURES

Single supply voltage from 8V to 22V

Internal 5V regulator

DESCRIPTION

The NX9415 is synchronous buck switching converter in

multi chip module designed for step down DC to DC

converter applications. It is optimized to convert bus

voltages from 8V to 22V to as low as 0.8V output volt-

age. The output current can be up to 5A. An internal

regulator converts bus voltage to 5V, which provides volt-

age supply to internal logic and driver circuit. The NX9415

operates from 200kHz to 2.2MHz and employs loss-less

current limiting by sensing the Rdson of synchronous

MOSFET followed by hiccup feature.Feedback under volt-

age protection triggers hiccup.

n Programmable frequency up to 2.2MHz

n Internal Digital Soft Start Function

n Internal boost schottky diode

n Prebias Startup

n Less than 50 nS adaptive deadband

Current limit triggers hiccup by sensing Rdson of

Synchronous MOSFET

n Pb-free and RoHS compliant

Other features of the device are: internal schottky diode,

thermal shutdown, 5V gate drive, adaptive deadband con-

trol, internal digital soft start, 5VREG undervoltage lock

out and shutdown capability via the comp pin. NX9415

is available in 4x4 MCM package.
