PWM BOOST CONTROLLER

PRODUCTION DATA SHEET

Pb Free Product

FEATURES

DESCRIPTION

The NX2158 controller IC is a boost controller IC de-

signed for step up DC to DC converter applications. The

NX2158 operates at programmable frequency from

200kHz to 2MHz and employs cycle by cycle current

limiting by sensing the Rdson of NMOSFET.

Single Supply Voltage fom 3V to 5.5V

n Programmable Frequency up to 2MHz

n Internal Digital Soft Start Function

Cycle by Cycle Current Limit by Sensing Rdson of

NMOSFET

Other features of the device are: thermal shutdown,

adaptive deadband control, internal digital soft start, VCC

UVLO and Shutdown capability via the ENBUS pin.

n Pb-free and RoHS compliant
