NCV8843
Buck Regulator, 1.5 A, 340 kHz, with Synchronization Capability
NCV8843
1.5 A, 340 kHz, Buck
Regulator with
Synchronization CapabilityThe 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.
FeaturesV2 Architecture Provides Ultra−Fast Transient Response, Improved
Regulation and Simplified Design Wide Operating Range: 4 V to 40 V 2.0% Error Amp Reference Voltage Tolerance Switch Frequency Decrease of 4:1 in Short Circuit Conditions
Reduces Short Circuit Power Dissipation BOOST Lead Allows “Bootstrapped” Operation to Maximize
Efficiency Sync Function for Parallel Supply Operation or Noise Minimization Shutdown Lead Provides Power−Down Option 1.0 �A Quiescent Current During Power−Down Thermal Shutdown Soft−Start Exposed Pad Packages for Enhanced Thermal Characteristics NCV Prefix for Automotive and Other Applications Requiring Site
