NCP5425DB

The NCP5425DB is a highly flexible dual buck controller with internal gate drivers that can be used with two input power supplies and one or two outputs in multiple configurations.

Features of the NCP5425DB are:(1)operation over 4.6 to 13.2 volts;(2)dual synchronous buck design;(3)configurable as a single two phase output or two single phase outputs;(4)programmable soft start;(5)100% duty cycle for enhanced transient response;(6)programmable power sharing and budgeting from two independent supplies;(7)0.8 volt ±1% reference for low voltage outputs;(8)1.5 A peak power drive;(9)switch blanking for noise sensitive applications through use of Rosc pin;(10)programmanle frequency ,150 kHz to 750 kHz operation;(11)cycle-by-cycle overcurrent protection;(12)independent programmable current limits;(13)internal slope compensation;(14)out-of-phase synchronization between the controllers;(15)input undervoltage lockout;(16)on/off enable through use of the COMP pins;(17) power supply sequencing.

The absolute maximum ratings of the NCP5425DB can be summarized as:(1):the parameter is operating junction temperature,the symbol is TJ,the value is 150,the unit is ;(2):the parameter is storage temperature range,the symbol is TS,the value is -65 to +150,the unit is ;(3):the parameter is ESD susceptiibity (human body model),the value is 2.0,the unit is kV;(4):the parameter is ESD susceptiibity (machine model),the value is 200,the unit is V;(5):the parameter is moisture sensitivity level,the value is 1;(6):the parameter is lead temperature soldering,the symbol is TL,the value is 260 peak,the unit is .
