NCP5422ADR2

The NCP5422ADR2 is a dual N-channel sychronous buck regulator controller. NCP5422ADR2 contains all the circuitry required for two independent buck regulator and utilizes the V2 control method to achieve the fastest possible transient response and best overall regulation,while using the least number of external components.

Features of the NCP5422ADR2 are:(1)V2 control topology;(2)hiccup mode overcurrent protection;(3)150 ns transient response;(4)programmable soft start;(5)100% duty cycle for enhanced transient response;(6)150 kHz to 600 kHz programmable frequency operation;(7)switching frequency set by single resistor;(8)out-of-phase synchronization between channels;(9)undervoltage lockout;(10)both gate drive outputs held low during fault condition.

The absolute maximum ratings of the NCP5422ADR2 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 package thermal resistance,SO-16 junction-to-case,the symbol is RJC,the value is 28,the unit is /W;(5):the parameter is package thermal resistance,SO-16 junction-to-ambient,the symbol is RJA,the value is 115,the unit is /W;(6):the parameter is lead temperature soldering,the symbol is TL,the value is 230 peak,the unit is .
