The NCV8843 is a 1.5 A buck regulator IC operating at a
fixed−frequency of 340 kHz. The device uses the V2 control
architecture to provide unmatched transient response, the best overall
regulation and the simplest loop compensation for today’s high−speed
logic. The NCV8843 accommodates input voltages from 4.0 V to 40 V
and contains synchronization circuitry.
The on−chip NPN transistor is capable of providing a minimum of
1.5 A of output current, and is biased by an external “boost” capacitor
to ensure saturation, thus minimizing on−chip power dissipation.
Protection circuitry includes thermal shutdown, cycle−by−cycle
current limiting and frequency foldback.
