1.5 A, 170 kHz, Buck Regulator with Synchronization Capability
**The NCV8842 is a 1.5 A buck regulator IC operating at a fixed−frequency
of 170 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 NCV8842 accommodates input voltages from 4.5 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.
Features
• V2 Architecture Provides Ultra−Fast Transient Response, Improved
Regulation and Simplified Design
• 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 μA Quiescent Current During Power−Down
• Thermal Shutdown
• Soft−Start
• Internally Fused Leads in SO−16L Package
• NCV Prefix for Automotive and Other Applications Requiring Site
and Control Changes
• Pb−Free Packages are Available -
